Revert "xwayland/glamor: Avoid implicit redirection with depth 32 parent windows" 

This commit is meant as an optimization, but has been identified as the
cause of multiple regressions reported in issues xorg/xserver#1564 and
xorg/xserver#1565.

Reverting that commit alone fixes the aforementioned issues, the rest of
the commits from xorg/xserver!1131 seem harmless and do not need
reverting.

This reverts commit d6c5999e94.
