perf/core, arch/x86: 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_NOEXCLUDE 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.

PMU drivers that support at least one exclude flag won't have the
PERF_PMU_CAP_NOEXCLUDE capability set - these PMU drivers should still
check and fail on unsupported exclude flags. These missing tests are
not added in this patch.
