Michel Dänzer 02236e3fda glamor: Don't override source alpha to 1.0 if it's used for blending 
It caused an incorrect result of the blend operation.

Use glColorMask to prevent non-1.0 alpha channel values in a depth 32
pixmap backing an effective depth 24 window. For blending operations,
the expectation is that the destination drawable contains valid pixel
values, so the alpha channel should already be 1.0.

Fixes: d1f142891e ("glamor: Ignore destination alpha as necessary for composite operation")
Issue: https://gitlab.gnome.org/GNOME/mutter/-/issues/3104
(cherry picked from commit d1bbf82d72)
