Add displayPresentTime to getFrameTimestamps
Makes HWC1 use displayRetireTime and HWC2 use
displayPresentTime.
Properly takes into account if HWC2On1Adapter is used.
Returns whether present or retire is supported via
eglQueryTimestampSupportedANDROID, which uses a
cached answer in Surface.
Surface::getFrameTimestamps returns with an error
if the caller requests an unsupported timestamp.
Test: adb shell /data/nativetest/libgui_test/libgui_test
