perf test: Expand user space event reading (rdpmc) tests
Test that disabling rdpmc support via /sys/bus/event_source/cpu*/rdpmc
disables reading in the mmap (libperf read support will fallback to
using a system call).
Test all hybrid PMUs support rdpmc.
Ensure hybrid PMUs use the correct CPU to rdpmc the correct
event. Previously the test would open cycles or instructions with no
extended type then rdpmc it on whatever CPU. This could fail/skip due
to which CPU the test was scheduled upon.
