Unlike fips_140_3, fips will be a (FIPS) version-agnostic build tag.
The listener support will remain in 140-3 only, but the IsFIPS() check
should apply regardless of FIPS version.
We add two FIPS-only build files which validate the constraints of FIPS
builds here: fips must be specified with either fips_140_2 or fips_140_3
build tags, and fips and cgo must also be specified together.
Additionally, using only a version-specific FIPS build tag without the
version-agnostic FIPS tag should be a failure.

* Warn user supplying nonce values in FIPS mode for transit encryption requests
- Send back a warning within the response if an end-user supplies nonce
values that we use within the various transit encrypt apis.
- We do not send a warning if an end-user supplies a nonce value but we
don't use it.
- Affected api methods are encrypt, rewrap and datakey
- The warning is only sent when we are operating in FIPS mode.
