[dev.boringcrypto] crypto/x509: remove VerifyOptions.IsBoring

This API was added only for BoringCrypto, never shipped in standard
Go. This API is also not compatible with the expected future evolution
of crypto/x509, as we move closer to host verifiers on macOS and Windows.

If we want to merge BoringCrypto into the main tree, it is best not to
have differing API. So instead of a hook set by crypto/tls, move the
actual check directly into crypto/x509, eliminating the need for
exposed API.

For #51940.
