[Telemetry] Migrate find_dependencies internals to tools/perf

Now that tools/perf/find_dependencies is the only find_dependencies, this CL
moves all the related under-the-hood code to tools/perf/core. It also moves the
davclient dependency out of tools/telemetry, since find_dependencies is the
only user of it.

BUG=528331
TEST=tools/perf/find_dependencies

Also move TELEMETRY_DEPS to tools/perf?

Done. I moved the salient contents of the file into the unit test directly, and
also removed the parts about file dependencies, as discussed offline.
