Multiple events in a group can belong to one or more pmus, however
there are some limitations to it. One of the limitation is, perf
doesn't allow creating a group of events from different hw pmus.
Write a simple test to create various combinations of hw, sw and
uncore pmu events and verify group creation succeeds or fails as
expected.

v1: https://lore.kernel.org/r/20221125032018.962-1-ravi.bangoria@amd.com
v1->v2:
 - #1 is new. It makes pmus list variable non-static and moves
   it to a new file.
 - Instead of hardcoded uncore pmu configuration, iterate over
   pmus list and use whichever first uncore pmu is available.
