[Intel-gfx] [PATCH 1/4] glamor: Added flags to indicate whether to use glamor in UXA.

[Zhigang Gong]

Added two new flags UXA_USE_GLAMOR and UXA_USE_GLAMOR_ONLY.
When UXA_USE_GLAMOR or UXA_USE_GLAMOR_ONLY is set, then it
will use GLAMOR to perform rendering operations by default.
If GLAMOR failed to accelerate the operation and UXA_USE_GLAMOR
is set, it then continue to the normal UXA code path to do
the rendering. If the UXA_USE_GLAMOR_ONLY is set, it then
jump to fallback path directly and avoid the UXA acceleration
code.
