[DesktopCapture][WGC] Avoid artifacts when capture source is resized

This CL fixes the issue where artifacts appear during capture with WGC
when the capture source is resized. A video of the issue is available
here: https://bugs.chromium.org/p/webrtc/issues/detail?id=9273#c44

The solution is to use CopySubresourceRegion instead of CopyResource to
only copy valid data into our texture. Additionally, we moved the call
to CreateMappedTexture to before the call to CopySubresourceRegion, as
the latter requires both textures to be of the same size.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
