Revert of [Mojo Video Capture] Hook up video capture service behind a feature flag (patchset #9 id:180001 of https://codereview.chromium.org/2867213004/ )
Reason for revert:
This CL appears to cause test failures on the Webkit Android bots for blink_heap_unittests and webkit_unit_tests.
Example failing build:
https://luci-milo.appspot.com/buildbot/chromium.webkit/WebKit%20Android%20%28Nexus4%29/65022
OSError: [Errno 2] No such file or directory: '/b/c/b/WebKit_Android__Nexus4_/src/out/Release/gen/services/video_capture/manifest.json'
Original issue's description:
> [Mojo Video Capture] Hook up video capture service behind a feature flag
>
> This CL is part of the Mojo Video Capture work. For the bigger picture,
> see [1] CL25.
>
> After this CL, the video capture service can be enabled by starting Chrome with
> command-line flag --enable-features=MojoVideoCapture.
>
> Changes in this CL:
> * Add a base::Feature kMojoVideoCapture to allow switching the service on and
> off.
> * Add a class VideoCaptureProviderSwitcher that can route device capture
> requests to the service's VideoCaptureProvider while routing screen capture
> requests to the InProcessVideoCaptureProvider.
> * Hook up the VideoCaptureProviderSwitcher in the factory code in
> MediaStreamManager.
> * Register video capture service in the service manager context for the Browser
> process.
> * Remove build flag "enable_mojo_video_capture", since we want the service to
> be testable in all builds.
> * Forward switches for using fake video capture devices to utility processes.
> * Add test cases for exercising the service to VideoCaptureBrowserTest.
