lib: move i915_wedged_set to ig_gt.c

Browse Source 
Upcoming tests will call it to recover from bad states caused by
hangcheck bugs.the function was renamed to igt_force_gpu_reset to have a
naming closer to other hang-related functions in the same file.

The value written to the debugfs has also been changed to -1; this makes
no differences with the current implementation but copes with upcoming
TDR changes (still under discussion) that should allow the resetting of
a mask of rings.
