Calcuates and reports frame buffer latencies
This change implements logics to calculate multiple frame buffer
latencies and reports them to statds and the users. For example, below
example shows LSHAL status dump with frame buffer latencies.
$ adb shell lshal debug \
android.hardware.automotive.evs@1.1::IEvsEnumerator/default \
--dump camera all --collected

Native (C++) code format is required to be compatible with .clang-format file. Run
git clang-format --style=file --extension='h,cpp,cc' HEAD~
Note that clang-format is not desirable for Android java files. Therefore the command line above is limited to specific extensions.
