Fixed bug on usage of GeneralJwsVerifier and improved its usability

[thehenrytsai]

1. Fixed bug where a new cache is created every time the DWN performs a signature check
2. Removed the need to instantiate a new instance of GeneralJwsVerifier every time DWN performs a signature check
3. Improved perf by not doing DID resolution when the signature check result is already cached
4. Minor error code naming improvements

Looks good! Just a comment in the tests, but isn't an actual problem.
