> Add ability to scale to arbitrary factors

> This CL adds a fallback for the case when no optimized scale factor produces a low enough resolution for what was requested. It also ensures that all resolutions provided by the video adapter are divisible by four. This is required by some hardware implementations.

A revert of this CL (patchset #1 id:1) has been created in
https://codereview.webrtc.org/2558243003/ by kthelgason@webrtc.org.

The reason for reverting is: There was a bug in the implementation where the
adapter could get stuck at really low resolutions. That has now been fixed..
