Filippo Valsorda 59211acb5d crypto/tls: disable SHA-1 signature algorithms in TLS 1.2
This implements RFC 9155 by removing support for SHA-1 algorithms:

  - we don't advertise them in ClientHello and CertificateRequest
    (where supportedSignatureAlgorithms is used directly)

  - we don't select them in our ServerKeyExchange and CertificateVerify
    (where supportedSignatureAlgorithms filters signatureSchemesForCertificate)

  - we reject them in the peer's ServerKeyExchange and CertificateVerify
    (where we check against the algorithms we advertised in ClientHello
    and CertificateRequest)
  
Fixes #72883
