Add a tag to xe_force_gt_reset that allows the user to decide whether or
not they want the reset to be synchronous or not.  This is done by
having the sys call target a new synchronous reset function when the tag
is set to true.

The new tag will be set to false by default, but the test
xe_exec_reset@cm-gt-reset will want this to be set to true because it
lacks a blocking mechanism on the reset and may race with itself
otherwise.
