Sameeh Jubran deb668ca4b pkcs7: add RSA-PSS support for SignedData

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.

formats

clean up trailing whitespace and misplaced CRLFs, add missing final newlines, remove stray UTF8 nonprintables (BOMs) and ASCIIfy stray homoglyphs (spaces and apostrophes), guided by expanded coverage in wolfssl-multi-test check-source-text.
