perf pmu: Detect ARM and hybrid PMUs with sysfs
is_arm_pmu_core detects a core PMU via the presence of a "cpus" file
rather than a "cpumask" file. This pattern holds for hybrid PMUs so
rename the function and remove redundant perf_pmu__is_hybrid
tests.
Add a new helper is_pmu_hybrid similar to is_pmu_core.
