This allows P256+SHA512 and P384+SHA512 signatures in certificates, when using the aws-lc-rs provider.

Previously, 0.23.32 added support for these in TLS1.2 handshake signatures. This was the topic of #2661 and #2477.

Note that (eg) Mozilla's Root Store Policy disallows such certificates. However, the reported case is a private CA, though the documentation for that CA also specifies that RSA keys are to be used? It's vibe certificates all the way down.

fixes #2825
