Move ProfileData out to its own file with helper
accessors. This keeps policy (what is/isn't jank)
outside of the data storage.
Also use lambdas to iterate over the histogram
to make it nicer for dumping & proto-ifying.
Test: hwui_unit_tests pass & jank data still dumps

* 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
