drm/xe: Add stats for vma page faults
Add new entries in stats for vma page faults. If CONFIG_DEBUG_FS is
enabled, the count and number of bytes can be viewed per GT in the
stat debugfs file. This helps when testing, to confirm page faults
have been triggered as expected. It also helps when looking at the
performance impact of page faults. Data is simply collected when
entering the page fault handler so there is no indication whether
it completed successfully, with or without retries, etc.
Example output:
cat /sys/kernel/debug/dri/0/gt0/stats
tlb_inval_count: 129
vma_pagefault_count: 12
vma_pagefault_bytes: 98304
v2: Rebase
