wfe: check well-formedness of requested names early (#7530)
This allows us to give a user-meaningful error about malformed names
early on, instead of propagating internal errors from the new rate
limiting system.

This moves the well-formedness logic from `WillingToIssue` into a new
function `WellFormedDomainNames`, which calls `ValidDomain` on each name
and combines the errors into suberrors if there is more than one.
`WillingToIssue` now calls `WellFormedDomainNames` to keep the existing
behavior. Additionally, WFE calls `WellFormedDomainNames` before
checking rate limits.

This creates a slight behavior change: If an order contains both
malformed domain names and wellformed but blocked domain names,
suberrors will only be generated for the malformed domain names. This is
reflected in the changes to `TestWillingToIssue_Wildcard`.

Adds a WFE test case for receiving malformed identifiers in a new-order
request.

Follows up on #3323 and #7218

Fixes #7526

Some small incidental fixes:

- checkWildcardHostList was checking `pa.blocklist` for `nil` before
accessing `pa.wildcardExactBlocklist`. Fix that.
- move table test for WillingToIssue into a new test case for
WellFormedDomainNames
 - move two standalone test cases into the big table test
