TL;DR: hybrid doesn't crash, json metrics work on hybrid on both PMUs
or individually, event parsing doesn't always scan all PMUs, more and
new tests that also run without hybrid, less code.

The first patches were previously posted to improve metrics here:
"perf stat: Introduce skippable evsels"
https://lore.kernel.org/all/20230414051922.3625666-1-irogers@xxxxxxxxxx/
"perf vendor events intel: Add xxx metric constraints"
https://lore.kernel.org/all/20230419005423.343862-1-irogers@xxxxxxxxxx/

Next are some general test improvements.

Next event parsing is rewritten to not scan all PMUs for the benefit
of raw and legacy cache parsing, instead these are handled by the
lexer and a new term type. This ultimately removes the need for the
event parser for hybrid to be recursive as legacy cache can be just a
term. Tests are re-enabled for events with hyphens, so AMD's
branch-brs event is now parsable.

The cputype option is made a generic pmu filter flag and is tested
even on non-hybrid systems.

The final patches address specific json metric issues on hybrid, in
both the json metrics and the metric code. They also bring in a new
json option to not group events when matching a metricgroup, this
helps reduce counter pressure for TopdownL1 and TopdownL2 metric
groups. The updates to the script that updates the json are posted in:
https://github.com/intel/perfmon/pull/73

The patches add slightly more code than they remove, in areas like
better json metric constraints and tests, but in the core util code,
the removal of hybrid is a net reduction:

There's specific detail with each patch, but for now here is the 6.3
output followed by that from perf-tools-next with the patch series
applied. The tool is running on an Alderlake CPU on an elderly 5.15
kernel:

Events on hybrid that parse and pass tests:
'''
$ perf-6.3 version
perf version 6.3.rc7.gb7bc77e2f2c7
$ perf-6.3 test
...
6.1: Test event parsing : FAILED!
...
$ perf test
...
6: Parse event definition strings :
6.1: Test event parsing : Ok
6.2: Parsing of all PMU events from sysfs : Ok
6.3: Parsing of given PMU events from sysfs : Ok
6.4: Parsing of aliased events from sysfs : Skip (no aliases in sysfs)
6.5: Parsing of aliased events : Ok
6.6: Parsing of terms (event modifiers) : Ok
...
'''

No event/metric running with json metrics and TopdownL1 on both PMUs:
