git: worktree_commit, Add crypto.Signer option to CommitOptions.

This change adds a new crypto.Signer option to CommitOptions as an
alternative to SignKey to allow alternative commit signers to be used.
This change byitself does not add other signing methods (e.g. ssh,
x509, gitsign), but gives callers the ability to add their own.

This roughly follows git's sign_buffer approach where go-git handles the
commit message body encoding, and hands off the encoded []byte to the signing
implementation for the signature to be returned.
