Use libcert_request_validator to check DICE chain
Remove one of the DICE chain validation implementations and replace it
with a call to the libcert_request_validator library which has the most
complete validation and is planned to be the only implementation we
support.
VTS will now check both degenerate and proper DICE chain more completely
and will be consistent with other tools like `bcc_validator`. P-384 will
become a supported key type in the DICE chain.
The whole static library is included so that clients that statically
link remote_prov_utils don't need to be aware of the dependency.
