The temp directory is made and a known fake hwmon PMU created within
it. Prior to this fix the events were being incorrectly written to the
temp directory rather than the fake PMU directory. This didn't impact
the test as the directory fd matched the wrong location, but it
doesn't mirror what a hwmon PMU would actually look like.

Incorrectly the hwmon with PMU name test didn't pass "true". Fix and
address issue with hwmon_pmu__config_terms needing to load events - a
load bearing assert fired. Also fix missing list deletion when putting
the hwmon test PMU and lower some debug warnings to make the hwmon PMU
less spammy in verbose mode.

In the error path when failing to parse events the evlist is being
deleted twice, keep the one after the out label.

Use name to avoid potential other hwmon PMUs.

Based on a mix of the sysfs PMU test (for creating the reference
files) and the tool PMU test, test that parsing given hwmon events
with there aliases creates the expected config values.

Filename parsing maps a hwmon filename to constituent parts enum/int
parts for the hwmon config value. Add a test case for the parsing.
