selftests/powerpc/pmu: Add selftest for group constraint check for radix_scope_qual field

Browse source

Testcase for group constraint check for radix_scope_qual field which is
used to program Monitor Mode Control Register (MMCR1) bit 18. All events
in the group should match radix_scope_qual bit, otherwise event_open for
the group should fail. Testcase uses "0x14242" (PM_DATA_RADIX_PROCESS_L2_PTE_FROM_L2)
with radix_scope_qual bit set for power10.
