Include extra HALs in dump state
- For debugging, more HALs including vendor HALs need to be included in
dumpstate.
- This CL includes HALs specified at read-only property
"ro.dump.hals.extra" when dumping processes.
Bug: 143622274
Test: Run dumpstate and check if HALs specified at "ro.dump.hals.extra"
property are included.
