Synchronize scanout pixmaps for TearFree
Copy the damaged areas which are still valid in the other scanout pixmap
from there, then only copy the remaining damaged area from the screen
pixmap.
This is slightly more efficient (only needs one Damage record instead of
two, and only needs to copy each screen update across PCIe once with
ShadowPrimary and a discrete GPU), and will be significantly more
efficient for PRIME with the following change.
