Michel Dänzer b0b3159abd present: Add present_vblank::exec_msc field ...

For tracking the MSC when the present can be executed separately from
the target MSC.

Allows removing the requeue field instead, plus more later.

v2:
* Rename wait_msc → exec_msc (Roman Gilg)
* Use exec_msc = target_msc instead of exec_msc++, for clarity.
* Bug fix: Set exec_msc = target_msc also if present_flip returned
  false in present_execute.
v3:
* Set exec_msc = target_msc also if present_wnmd_flip returned
  false in present_wnmd_execute, for consistency.
v4:
* Specifically check for exec_msc == crtc_msc + 1 in
  present_execute_wait/copy, to avoid re-introducing
