selftests/powerpc/pmu: Add interface test for mmcra_ifm field for conditional branch type
The testcase uses "instructions" event to check if the Instruction filtering mode(IFM) bits are programmed correctly for conditional branch type. Testcase checks if IFM bits is programmed correctly to Monitor Mode Control Register A (MMCRA) via perf interface for ISA v3.1 platform.
