MountService: Add support for multiple storage configurations

Currently AOSP only supports a single storage configuration that is hardcoded
in storage_list.xml. Some device updates are now merging data and internal
storage partitions, and as a result require the storage list to support two
different variations.

By utilizing the sys.storage_legacy property this will allow for the framework
to support multiple configurations which can be determined during boot.

perf: Don't persist the perf profile across a reboot

 * Always initialize with the default performance profile.
 * There are a lot of reasons for this, but mostly because
   users are stumbling into the setting and ending up with a
   slow system because they enabled powersave mode.

perf: Send a boost hint when a key on the navbar is pressed

 * A lot of stuff happens, especially when invoking recents.
 * Get ahead of the storm by sending a boost hint before
   kicking off the animations.
