2018 PowerHAL support for master stats

Implementation of PowerHAL stats collection for 2018 subsystems/
masters.  Adds support for SOC masters: APSS, MPSS, ADSP, SLPI, CDSP,
GPU, and DISPLAY (though the last 3 do not currently provide any stats
from the rpmh_master_stats driver).  Also adds support for the two new
system power states: AOSD and CXSD.  In a change from earlier devices,
getPlatformLowPowerStats() now only returns stats for those two power
states, since there are no matter "voting" stats.  The stats for all
masters and subsystems (e.g. WLAN) are now retrieved through
getSubsystemLowPowerStats().

Also updates (or removes) old stale sepolicy entries related to low
power stats files that no longer exist, updates device dumpstate support
to add one of the two stats files that does exist but isn't currently
included, and pulls in the wahoo fix to ensure that stats are available
even in user builds.

Bug: 67381845
Bug: 74405843
Test: Confirmed divisor for RPMh stats is the same as old RPM divisor
(19200 to get msecs) by checking logged clock frequency and manually
manipulating the sleeping of an easily influenced master (ADSP) and
comparing entry and exit times.
Test: Built and ran a user build and verified that low power stats are
properly accessible by collecting a bugreport.
Test: Added test code to rpmh_master_stats driver to populate bogus data
for masters that don't have data available and used that to verify that
parsing of stats for all sections is working correctly.
Test: Compared audit2allow output from bugreport generation on before
and after builds to verify that no new sepolicy issues were introduced.
