windows: add a global equivalent to /etc/mercurial for *.rc processing

This follows the Unix model of processing this directory immediately after
<internal>/*.rc, and prior to the installation relative files.  Since the Unix
processing supports both a directory and a file (the former overriding the
latter), and since %HOME% supports both `*.ini` and `.hgrc` (again, the former
overriding the latter), this does too.  The Unix file doesn't have a `.` prefix,
so it's not used here either.

Note that this is the opposite order of processing the exe relative paths.  But
since it's in agreement with Unix, %HOME% and %USERPROFILE%, it seems reasonable
to ignore that.  Maybe we can change that and take a BC, because that's
something the installer should be controlling, and I can't imagine people having
both paths *and* conflicting settings.
