run-tests: add substitution patterns for common '\' path output on Windows
The goal is to reduce the amount of hand tuning of new/changed tests that is
required on Windows. Since the OS prints the proper paths everywhere else, this
is limited to Windows. These are based on the check-code rules that were
dropped in 5feb782c7a95.
There are some minor tweaks, because those were trying to detect '/' paths
without a '(glob)' at the end, whereas these detect '\' paths. Also, it looks
like the 'no changes made to subrepo' one was broke, because the path to the
subrepo has been getting output but was not in the pattern. End anchors are
dropped because '(glob)' is no longer required, but '(feature !)' annotations
are a possibility.
The 'saved backup bundle' pattern dropped from run-tests.py was simply carrying
over the first capture group. The replace() method runs prior to evaluating
'\1', but it wasn't doing anything because of the 'r' prefix on '\\'.
The 'not recording move' entry is new, because I stumbled upon it searching for
some of these patterns. There are probably others.
