Many GLAMOR OpenGL ES Improvements Backported To X.Org Server / XWayland 21.1

Nearly one year after the merge request was first opened, back-ported now to the X.Org Server 21.1 stable branch are a number of GLAMOR 2D acceleration fixes around OpenGL ES 2.x as well as supporting OpenGL ES 3.x shaders for this generic 2D acceleration over OpenGL for the xorg-server and XWayland.

In August of last year Konstantin opened the merge request to back-port a number of GLAMOR fixes from the latest X.Org Server master code to the 21.1 branch given that X.Org Server 21.1 with point releases have continued and no signs of a major xorg-server release on the horizon.

This includes many OpenGL ES fixes for GLAMOR, GLES3 shader support, accelerating incomplete textures for GLES, adding an option for choosing between OpenGL and OpenGL ES, an Xv optimization, and other fixes.

This merge after being open for 11 months and containing more than three dozen patches is now back-ported to the X.Org Serve 21.1 branch for whenever the next point release is to happen... Presumably in time for the next security disclosure(s). This also benefits XWayland.
