perf tests: Add breakpoint accounting/modify test
Adding test that:
- detects the number of watch/break-points,
skip test if any is missing
- detects PERF_EVENT_IOC_MODIFY_ATTRIBUTES ioctl,
skip test if it's missing
- detects if watchpoints and breakpoints share
same slots
- create all possible watchpoints on cpu 0
- change one of it to breakpoint
- in case wp and bp do not share slots,
we create another watchpoint to ensure
the slot accounting is correct
