When an envelope transformer calls out to KMS (for instance), it will be
very helpful to pass a `context.Context` to allow for cancellation. This
patch does that, while passing the previously-expected additional data
via a context value.

This change updates NewPrefixTransformers to not short-circuit on
the first transformer that has a matching prefix. If the same type
of encryption ProviderConfiguration is used more than once, they
will share the same prefix. A failure in the first one should not
prevent a later match from being attempted.
Added TestCBCKeyRotationWithOverlappingProviders unit test to
prevent regressions. Note that this test explicitly exercises this
flow using an EncryptionConfiguration object as the structure of the
resulting transformer is an important part of the check.
