[PATCH i-g-t v2 44/66] tests/xe_exec_sip: Add breakpoint-waitsip-heavy test

[Christoph Manszewski]

From: Dominik Karol Piątkowski <dominik.karol.piatkowski at intel.com>

Add breakpoint-waitsip-heavy test that walks checks if we reset
after seeing the attention from heavy SIP without the debugger.
