perf/core, arch/arm: Use PERF_PMU_CAP_NO_EXCLUDE for exclusion incapable PMUs

For drivers that do not support context exclusion let's advertise the
PERF_PMU_CAP_NO_EXCLUDE capability. This ensures that perf will
prevent us from handling events where any exclusion flags are set.
Let's also remove the now unnecessary check for exclusion flags.
