[PATCH v4 0/2] perf tests: Add uncore and x86 topdown event sorting tests

[Ian Rogers <irogers@google.com>]

A patch thread changing event sorting highlighted a lack of testing
for the more complicated uncore and x86 perf metric event sorting:

v4: Fix malformed event group string formatting in the uncore event
    sorting test when running on AMD systems (where sysfs event
    aliases lack JSON descriptions - reported by Namhyung). Added a
    helper to strip redundant PMU prefixes and trailing slashes to
    ensure parse_events() receives valid syntax across all
    architectures.

v3: Address sashiko nits on using evsel__name and ensuring slots is injected.

v2: Address indentation and other nits from Namhyung. Add Zide Chen's
    tested-by tags.
