Remove the ability for the issuance package to include the AIA OCSP URI
and the Must Staple (more properly known as the tlsRequest) extension in
certificates. Deprecate the "OmitOCSP" and "AllowMustStaple" profile
config keys, as they no longer have any effect. Similarly deprecate the
"OCSPURL" issuer config key, as it is no longer included in
certificates.
Update the tests to always include to CRLDP extension instead, and
remove some OCSP- or Stapling-specific test cases.

Remove the backwards-compatible profile hashing code. It is no longer
necessary, since all deployed profile configs now set
IncludeCRLDistributionPoints to true and set the UnsplitIssuance flag to
true. Catch up the CA and crl-updater configs to match config-next and
what is actively deployed in prod.

To achieve this without breaking hashes of deployed configs, create a
ProfileConfigNew containing the new field (and removing some deprecated
fields).
Move the CA's profile-hashing logic into the `issuance` package, and
gate it on the presence of IncludeCRLDistributionPoints. If that field
is false (the default), create an instance of the old `ProfileConfig`
with the appropriate values and encode/hash that instead.
Note: the IncludeCRLDistributionPoints field does not yet control any
behavior. That will be part of #7974.

This brings in several new and useful lints. It also brings in one CABF
BR lint which we have to ignore in our default profile which includes
the Subject Key Identifier extension:
"w_ext_subject_key_identifier_not_recommended_subscriber". In our modern
profile which omits several fields, we have to ignore the opposite
RFC5280 lint "w_ext_subject_key_identifier_missing_sub_cert".

Note that the majority of the ~400 file changes are merely copyright
date changes.
The corresponding production config changes tracked in IN-10466 are
complete.
Goodkey has two ways to detect a key as weak: it runs a variety of
algorithmic checks (such as Fermat factorization and rocacheck), or the
key can be listed in a "weak key file". Similarly, it has two ways to
detect a key as blocked: it can call a generic function (which we use to
query our database), or the key can be listed in a "blocked key file".
This is two methods too many. Reliance on files of weak or blocked keys
introduces unnecessary complexity to both the implementation and
configuration of the goodkey package. Remove both "key file" options and
delete all code which supported them.
Also remove //test/block-a-key, as it was only used to generate these
test files.
IN-10762 tracked the removal of these files in prod.

Move the two lint-configuration keys, LintConfig and IgnoreLints, from
the top-level CA.Issuance config stanza into each individual
CA.Issuance.CertProfiles stanza. This allows us to have
differently-configured lints for different profiles, to ensure that our
linting regime is as strict as possible.
Without this change, it would be necessary for us to ignore both the
"common name included" and the "no subject key id" lints at the
top-level, when in fact each of those warnings only triggers on one of
our two profiles.
Fixes https://github.com/letsencrypt/boulder/issues/7635
Add a new profile config key named "OmitCommonName" which, if set to
`true`, causes the issuance package to exclude the CN from the resulting
certificate even if the initiating IssuanceRequest specified one.
Deprecate the old "AllowCommonName" config key, so that it no longer has
any effect, rather than causing the issuance package to fully reject
IssuanceRequests containing a CN.
This allows for more graceful variation between profiles, since we know
that excluding the Common Name is always safe.

The summary here is:
- Move test/cert-ceremonies to test/certs
- Move .hierarchy (generated by the above) to test/certs/webpki
- Remove our mapping of .hierarchy to /hierarchy inside docker
- Move test/grpc-creds to test/certs/ipki
- Unify the generation of both test/certs/webpki and test/certs/ipki
into a single script at test/certs/generate.sh
- Make that script the entrypoint of a new docker compose service
- Have t.sh and tn.sh invoke that service to ensure keys and certs are
created before tests run
No production changes are necessary, the config changes here are just
for testing purposes.

Replace the CA's "useForRSA" and "useForECDSA" config keys with a single
"active" boolean. When the CA starts up, all active RSA issuers will be
used to issue precerts with RSA pubkeys, and all ECDSA issuers will be
used to issue precerts with ECDSA pubkeys (if the ECDSAForAll flag is
true; otherwise just those that are on the allow-list). All "inactive"
issuers can still issue OCSP responses, CRLs, and (notably) final
certificates.
Instead of using the "useForRSA" and "useForECDSA" flags, plus implicit
config ordering, to determine which issuer to use to handle a given
issuance, simply use the issuer's public key algorithm to determine
which issuances it should be handling. All implicit ordering
considerations are removed, because the "active" certificates now just
form a pool that is sampled from randomly.
To facilitate this, update some unit and integration tests to be more
flexible and try multiple potential issuing intermediates, particularly
when constructing OCSP requests.
For this change to be safe to deploy with no user-visible behavior
changes, the CA configs must contain:
- Exactly one RSA-keyed intermediate with "useForRSALeaves" set to true;
and
- Exactly one ECDSA-keyed intermediate with "useForECDSALeaves" set to
true.
If the configs contain more than one intermediate meeting one of the
bullets above, then randomized issuance will begin immediately.

Move the CRL issuance logic -- building an x509.RevocationList template,
populating it with correctly-built extensions, linting it, and actually
signing it -- out of the //ca package and into the //issuance package.
This means that the CA's CRL code no longer needs to be able to reach
inside the issuance package to access its issuers and certificates (and
those fields will be able to be made private after the same is done for
OCSP issuance).
Additionally, improve the configuration of CRL issuance, create
additional checks on CRL's ThisUpdate and NextUpdate fields, and make it
possible for a CRL to contain two IssuingDistributionPoint URIs so that
we can migrate to shorter addresses.
IN-10045 tracks the corresponding production changes.

Remove the Profile field from issuance.Issuer, to reflect the fact that
profiles are in fact independent pieces of configuration which can be
shared across (and are configured independently of) multiple issuers.
Move the IssuerURL, OCSPUrl, and CRLURL fields from issuance.Profile to
issuance.Issuer, since they reflect fundamental attributes of the
issuer, rather than attributes of a particular profile. This also
reflects the location at which those values are configured, in
issuance.IssuerConfig.
All other changes are fallout from the above: adding a Profile argument
to various methods in the issuance and linting packages, adding a
profile field to the caImpl struct, etc. This change paves the way for
two future changes: moving OCSP and CRL creation into the issuance
package, and supporting multiple simultaneous profiles that the CA can
select between.

Upgrade to zlint v3.6.0
Two new lints are triggered in various places:
aia_contains_internal_names is ignored in integration test
configurations, and unit tests are updated to have more realistic URLs.
The w_subject_common_name_included lint needs to be ignored where we'd
ignored n_subject_common_name_included before.

This will make it easier to add a crl.go, holding functionality similar
to cert.go, without making any single file overly complex.
This introduces no functionality changes.
