Initial work in this area landed in https://chromium-review.googlesource.com/c/chromium/src/+/2440055

This CL adds two new UMA histograms:

1) Media.Audio.Capture.Win.DefaultEffectType
2) Media.Audio.Capture.Win.RawEffectType

Each histogram can contain 17 different values and they indicate support
of different audio effect components such as AEC, NS, AGC etc. The idea
is to monitor how common each of these audio effects are.

There is one histogram for each audio processing mode: Default and Raw.

The CL changes no real-time functionality but it uses Windows UWP APIs
to enumerate the supported and active capture effects when opening
audio input streams on Windows.
