EGL: Enable eglGetFrameTimestamps.

Also clean up the specification description:
1) Reverse order of revision history notes.
2) Specifically mention polling from another thread.
3) Make it explicit that eglQueryTimestampSupportedANDROID
   works for the timestamps of both eglGetCompositorTimingANDROID
   and eglGetFrameTimestampsANDROID.

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