Update when/how `requested_resolution` throws for invalid parameters.

This CL makes `requested_resolution`, which is the C++ name for what
the spec calls scaleResolutionDownTo, align with the latest PR[1].

The PR says to ignore scaleResolutionDownBy when scaleResolutionDownTo
is specified as to be backwards compatible with scaleResolutionDownBy's
default scaling factors (e.g. 4:2:1). Ignoring is different than what
the code does today which is to throw an InvalidModificationError.

We don't want to throw or else get+setParameters() would throw by
default due to 4:2:1 defaults so the app would have to remember to
delete these attributes every time even though it never specified them
(Chrome has a bug here but fixing that would expose this problem, see
https://crbug.com/344943229).

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
