fix(did-comm): remove isomorphic-webcrypto dependency

[mirceanis]

What issue is this PR fixing

fixes #1381
fixes #1387

What is being changed

Removed isomorphic-webcrypto dependency in favor of @noble/ciphers + @noble/hashes.
This also allowed us to remove several other @stablelib/* dependencies from the @veramo/did-comm package.

I also updated the encryption tests to include the test-vectors that were previously unused.
