Update Alternating Interrupt/Resume Test

[Jemale]

Updates the test to retry interrupting threads
in case the threads were unavailable/not resumed
when initial interrupt request sent

@Jemale is this PR fixing some test case?

we should be watiing in dbgUMD when resuming threads - until they are resumed.
so zeDebugResume() - should make sure that threads are resumed before returning from the function.

if delaying interrupt helps - this may be something in dbgUMD or KMD that makes interrupt non effective - like treating threads as accidentally stopped and silently resuming them ( due to some timing reading ATT events, processing interrupts and reading ATT event again )
