notes: Add git_note_commit_create

This adds a new function that will allow creation of notes without
necessarily updating a particular ref, the notes tree is obtained
from the git_commit object parameter, a new commit object pointing
to the current tip of the notes tree is optionally returned
via the 'note_commit_out' parameter,
optionally the blob id for the note is returned through
the 'note_blob_out' object.
