Add ANDROID_JANK_CORRELATE_FRAME_SLICE

Adding a couple of functions as wrappers over a helper SQL script used
to run queries against traces - it allows matching long slice durations
with (missed) frames. This can be used as a heuristic to figure out what
contributed to frames missing their expected deadlines.
