On VHAL death unsubscribe from VHAL heartbeats and remove vhal messages.

- In WatchdogProcessService#terminate(), unsubscribe the
mProperyChangeListener and remove MSG_VHAL_HEALTH_CHECK messages from
the handler.
- In WatchdogProcessService#handleHidlDeath, remove MSG_VHAL_HEALTH_CHECK
messages from the handler. This ensures that WatchodgProcessService
doesn't try to terminate VHAL after it died.

Native (C++) code format is required to be compatible with .clang-format file. Run

git clang-format --style=file --extension='h,cpp,cc' HEAD~

Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
