RSA-PSS signed certificates contain a valid RSA public key that can be
used for key transport, but wc_PKCS7_AddRecipient_KTRI and the
EnvelopedData/AuthEnvelopedData encode paths rejected them because they
only checked for RSAk. Allow RSAPSSk to fall through to the RSAk key
transport path, and always use RSAk as the KeyEncryptionAlgorithmIdentifier
since the operation is RSA encryption, not RSA-PSS signing.

Add full RSA-PSS (RSASSA-PSS) support to PKCS#7 SignedData
encoding and verification.
This change enables SignerInfo.signatureAlgorithm to use
id-RSASSA-PSS with explicit RSASSA-PSS-params (hash, MGF1,
salt length), as required by RFC 4055 and CMS profiles.
Key changes:
- Add RSA-PSS encode and verify paths for PKCS7 SignedData
- Encode full RSASSA-PSS AlgorithmIdentifier parameters
- Decode RSA-PSS parameters from SignerInfo for verification
- Treat RSA-PSS like ECDSA (sign raw digest, not DigestInfo)
- Fix certificate signatureAlgorithm parameter length handling
- Add API test coverage for RSA-PSS SignedData
This resolves failures when using RSA-PSS signer certificates
(e.g. -173 invalid signature algorithm) and maintains backward
compatibility with RSA PKCS#1 v1.5 and ECDSA.
