EGL: Add eglGetCompositorTimingANDROID.

Exposes the composite deadline, composite interval, and
the composite to present latency.

A history of composite and present fences are stored.
When the present fence's timestamp becomes known,
the composite to present latency is updated with
sampling jitter removed.

The values are updated in the producer when timestamps
are enabled and on queue and dequeue.

The deadline is snapped to the next expected deadline
based on the current systemTime().

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