builtin-notes: Add "list" subcommand for listing note objects

"git notes list" will list all note objects in the current notes ref (in the
format "<note object> <annotated object>"). "git notes list <object>" will
list the note object associated with the given <object>, or fail loudly if
the given <object> has no associated notes.

If no arguments are given to "git notes", it defaults to the "list"
subcommand. This is for pseudo-compatibility with "git tag" and "git branch".

The patch includes tests verifying correct behaviour of the new subcommand.
