Capturing window thmubnails is expensive as it actually uses the
window capturer and it records one full frame per window and then
downscale to the default size 150x150. When only interested in the
window names or the app icons we do not need all of this.
Underlying change is merged in chromium72 so this patch only modifies
the doc, see:
https://chromium.googlesource.com/chromium/src.git/+log/72.0.3626.52/chrome/browser/media/webrtc/native_desktop_media_list.cc
Example: desktopCapturer.getSources({thumbnailSize: {width: 0, height: 0}}, ...)
Also added a unit test in spec/api-desktop-capturer-spec.js that verifies
that the returned thumbails are of type NativeImage and empty,
when the user disable fetching thumbnails.
notes: Can disable fetching the thumbnails for the DesktopCapturer.

* fix: create a window capturer correctly
We were incorrectly creating two screen capturers instead of a window
capturer
* spec: ensure dc tests pass
* spec: enable all tests after verifying dc tests work
* Make it possible to disable a module for a renderer
* Put DesktopCapturer API under a build flag
The name is "enable_desktop_capturer".
Enabled by default.
* Add a screen_api_id parameter to the desktopCapturer API.
When using the DirectX capturer on Windows, there was previously no way
to associate desktopCapturer/getUserMedia and electron.screen API
screens. This new parameter provides the association.
* Fix non-Windows build.
* Fix Mac.
* Fix Mac harder.
* JS lint
* clang-format C++ code.
* IWYU
* display_id, Linux comment, better test
* lint
* Fix tests on Linux.
* Add display_id documentation.
