Add additional information to each VM so they can report up to the last
50 seen pagefaults.  Only failed pagefaults are saved this way, as
successful pagefaults should recover and not need to be reported to
userspace.

Additionally, add a new ioctl - xe_vm_get_property_ioctl - that allows the
user to query these pagefaults

v2: (Matt Brost)
- Break full ban list request into a separate property.
- Reformat drm_xe_vm_get_property struct.
- Remove need for drm_xe_faults helper struct.
- Separate data pointer and scalar return value in ioctl.
- Get address type on pagefault report and save it to the pagefault.
- Correctly reject writes to read-only VMAs.
- Miscellaneous formatting fixes.

v3: (Matt Brost)
- Only allow querying of failed pagefaults

v4:
- Remove unnecessary size parameter from helper function, as it
  is a property of the arguments. (jcavitt)
- Remove unnecessary copy_from_user (Jainxun)
- Set address_precision to 1 (Jainxun)
- Report max size instead of dynamic size for memory allocation
  purposes.  Total memory usage is reported separately.

v5:
- Return int from xe_vm_get_property_size (Shuicheng)
- Fix memory leak (Shuicheng)
- Remove unnecessary size variable (jcavitt)
