glamor: Add Option "ShadowPrimary" v2

When this option is enabled, most pixmaps (including the screen pixmap)
are allocated in system RAM and mostly accessed by the CPU. Changed areas
of the screen pixmap are copied to dedicated per-CRTC scanout pixmaps
regularly, triggered by the vblank interrupt.

v2:
* Set region data pointer to NULL for keeping only the extents
* Move pRegion and pBox local variable declarations closer to their uses
  in drmmode_set_mode_major()
