Add a new xe_force_gt_reset function, xe_force_gt_reset_sync, renaming
the original xe_force_gt_reset to xe_force_gt_reset_async.  This allows
the user to decide whether or not they want to initiate a synchronous or
asynchronous gt reset.  The asynchronous reset function was otherwise
unchanged, but the synchronous reset function operates by calling a new
debugfs function.

Tests will use the asynchronous gt reset function by default, but the
test xe_exec_reset@cm-gt-reset will want to use the synchronous version
because it lacks a blocking mechanism on the reset and may race with
itself otherwise.

v2:
- Create a new function for synchronous gt reset instead of using a tag
  to denote between the two modes
