android: Add GN dependency graph to stats

Previously only the actual jdeps graph was used, and it was missing
additional deps that are only in GN. This CL also parses the GN target
dep from project.json.

The script now requires passing `-C` or `--out-dir` for the output
directory in which to generate project.json.

Skip testonly targets and targets with 'test' in their name by default.
Pass --include-testonly to add them back.

Add some targets that the annotator regularly misses (e.g. annotations,
errorprone, profiling) as these are not blockers for other targets to be
annotated.

Allow verbose output to show more information about each target and
which other targets they depend on.

Improve transitive dep detection to account for up to 2^5 = 32 deep
dep-chains. i.e. A1 depends on A2 ... depends on A32 should all be
resolved in the transitive dep graph correctly.

Takes less than 2 minutes with --no-cache, and 15 seconds with a full
cache (i.e. /tmp files and existing project.json file).
