Intent to remove: wm/quartz-wm

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

In http://gnats.netbsd.org/55880, someone tried to build quartz-wm on
Apple Silicon and found out it doesn't work. Upstream has been dead
for several years, and they state:  "The functionality
provided by this binary has been merged into libXplugin on newer
versions of OS X." (This was in 2015!)

Thus, it no longer seems useful to have a quartz-wm package. Does
anyone object? I would like to remove it some time after the branch.
