Overhaul GraphicsStatsService

* LRU cache of recently-used is dead, replaced
  disk storage
* ASHMEM size is read from native by the system service,
  no longer requires keeping a sizeof() in sync with a
  constant in Java
* Supports dumping in proto format by passing --proto
* Rotates logs on a daily basis
* Keeps a history of the most recent 3 days

Bug: 33705836
Test: Manual. Verified log rotating works by setting it up to
rotate every minute instead of day. Confirmed /data/system/graphicsstats
only has the most recent 3 entries after several minutes
