Cache frame event history producer-side.

* Producer maintains a recent history of frames.
* Producer only does a binder call if requested
    informatiVon doesn't exist in the cache.
* Consumer sends fences to the producer, which
    can be queried for timestamps without a
    binder call.

Test: adb shell /data/nativetest/libgui_test/libgui_test
--gtest_filter=*GetFrameTimestamps*
