Andrew Murray 88dbe3c94e perf/core, arch/x86: Strengthen exclusion checks with PERF_PMU_CAP_NO_EXCLUDE
For x86 PMUs 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.

This change means that amd/iommu and amd/uncore will now also
indicate that they do not support exclude_{hv|idle} and intel/uncore
that it does not support exclude_{guest|host}.
