Revert of DevTools socket tunnel.

Revert of DevTools socket tunnel. (patchset #11 id:300001 of https://codereview.chromium.org/517233002/)

Reason for revert:
Fails to compile on Android: https://build.chromium.org/p/chromium.linux/builders/Android%20Arm64%20Builder%20(dbg)/builds/2163

devtools_bridge/android/javatests/src/org/chromium/components/devtools_bridge/SocketTunnelServerTest.java:291: cannot find symbol
symbol: method sleep()
                sleep();

Original issue's description:
> Implementation of DevTools socket tunneling service for remote debugging.
>
> Test APK in addition to instrumentation tests contains launching activity and foreground service what let duplicate ChromeShell debug socket to a differently named socket. If a device with running ChromeShell and DevToolsBridgeTest's service connect to a Desktop chrome (with USB debugging enabled) then chrome://inspect#devices will show 2 ChromeChell items. Both are debuggable (https://codereview.chromium.org/521573002/ should be applied to Desktop chrome to make the process less surprising). It's suitable for manual tests.
>
> This CL doesn't care of a few known issues:
> 1. Data channel buffer overflow. Data channel automatically closed in this case.
> 2. Uncontrolled number of pending sockets. DevTools throttles opening sockets and and keeps sockets that exceeds a threshold hanging.
> 3. Uncontrolled number of threads (it's actually not a problem if #2 solved, thanks to DevTools throttling).
>
> To keep this CL reasonably simple this issues will be addressed later.
>
> TEST=org.chromium.components.devtools_bridge.SocketTunnelServerTest, see description fro manual testing.
