In commit 1d3351e631 ("perf tools: Enable on a list of CPUs for hybrid")
perf on hybrid will warn if a user requested CPU doesn't match the PMU
of the given event but only for hybrid PMUs. Make the logic generic
for all PMUs and remove the hybrid logic.
Warn if a CPU is requested that isn't present/offline for events not
on the core. Warn if a CPU is requested for a core PMU, but the CPU
isn't within the cpu map of that PMU.
For example on a 16 (0-15) CPU system:
```
$ perf stat -e imc_free_running/data_read/,cycles -C 16 true
WARNING: A requested CPU in '16' is not supported by PMU 'uncore_imc_free_running_1' (CPUs 0-15) for event 'imc_free_running/data_read/'
WARNING: A requested CPU in '16' is not supported by PMU 'uncore_imc_free_running_0' (CPUs 0-15) for event 'imc_free_running/data_read/'
WARNING: A requested CPU in '16' is not supported by PMU 'cpu' (CPUs 0-15) for event 'cycles'
Performance counter stats for 'CPU(s) 16':
<not supported> MiB imc_free_running/data_read/
<not supported> cycles
0.000575312 seconds time elapsed
```
Remove evlist__fix_hybrid_cpus that previously produced the warnings
and also perf_pmu__cpus_match that worked with evlist__fix_hybrid_cpus
to change CPU maps for hybrid CPUs, something that is no longer
necessary as CPU map propagation properly intersects user requested
CPUs with the core PMU's CPU map.
