Address CI failure related to reset [1]. In addition to the public CI failure we also fix several issues uncovered recenting in our internal CI related to resets. Patch #1 address all of these issues.
Workaround an existing memory corruption, in gt_lrc selftest, exposed by enabling GuC submission [2].
Lastly, add a selftest to give us confidence in some of the reset code that is rather hard / intermittent to exercise via IGTs.
