glamor: Implement GetSupportedModifiers

Browse Source 
Implement function added in DRI3 v1.1.

A newest version of libepoxy (>= 1.4.4) is required as earlier
versions use a problematic version of Khronos
EXT_image_dma_buf_import_modifiers spec.

v4: Only send scanout-supported modifiers if flipping is possible
v5: Fix memory corruption in XWayland (uninitialized pointer)
