Revert 230553 "Added AVFoundation Glue and Device Monitoring for..."

Patch reverted by request of the author.

> Added AVFoundation Glue and Device Monitoring for Mac.
> 
> This CL adds files called avfoundation_glue.{h,mm} to media/video/capture/mac.
> These files encapsulate dynamic loading of AVFoundation libraries and define+
> implement a facade to the used AVFoundation classes. The first usage of those
> is the DeviceMonitorMac, where the original QTKit event class is transformed
> into an interface (MacMonitorInterface), implemented by both QTKitMonitorImpl
> and AVFoundationMonitorImpl. the usage of one or the other is decided on
> DeviceMonitorMac constructor time.
> 
> This CL is part of a larger exercise to add support for Video Capture in
> Mac > 10.6 using AVFoundation.
> 
> BUG=288562

-// AVFoundation API is only introduced in Mac OS X > 10.6, and there is only one
-// build of Chromium, so the (potential) linking with AVFoundation has to happen
-// in runtime. For this to be clean, a AVFoundationGlue class is defined to try
-// and load these AVFoundation system libraries. If it succeeds, subsequent
-// clients can use AVFoundation via the rest of the classes declared in this
-// file.
