[PATCH i-g-t] tests/xe_eudebug_online: breakpoint-many-sessions-* add delay before resume

[Maciej Patelczyk]

For single tile workloads under debug are executed sequentially.
The test quickly resumes workload that hit the breakpoint without any
delay. That is then catched by the expectation that there shall be a
break between workloads.

Add sleep before resuming workload so that there is a forced gap
between workloads. If they were properly executed sequentially
then the diff between workloads shall be longer than sleep.

Additionally fix the 'ms' to 'us' typo report in case of assert.
