Removing WebRTC Java API

Removing WebRTC Java API

It's not used any longer.

Was added in https://codereview.chromium.org/551793003/ as temporary solution to use WebRTC from android service.

In following CLs we've moved to native API:
https://codereview.chromium.org/704613003
https://codereview.chromium.org/716433003
https://codereview.chromium.org/719043002
https://codereview.chromium.org/734313002

There is no plan to use Java API for DevTools bridge again.

This is a rebase of https://codereview.chromium.org/767073002/ . As I'm not the
owner of the CL, I couldn't update the original one.

lgtm, thanks for finishing this cleanup.

IMO such targets should belong in the libjingle code (which is in progress of
being migrated into the WebRTC codebase), to the less we can have in these
Chromium GYP/GN files, the better.
