drm/xe: Add more GT stats around pagefault mode switch flows

Browse source

Add GT stats to measure the time spent switching between pagefault mode
and dma-fence mode. Also add a GT stat to indicate when pagefault
suspend is skipped because the system is idle. These metrics will help
profile pagefault workloads while 3D and display are enabled.

v2:
 - Use GT stats helper functions (Francois)
