Revert "Adds experimental libvpx VP9 speed settings."

This reverts commit 6e7167456b5eba36c7985d6a74f1d191958d4e0f.

Reason for revert: Unexpected perf change

Original change's description:
> Adds experimental libvpx VP9 speed settings.
>
> Using the field trial WebRTC-VP9-PerformanceFlags, this CL allows you to
> configure the libvpx VP9 encoder with a list of flags to affect the
> quality vs speed tradeoff. This CL adds support for:
>
> * Speed (effort), for the temporal base layer frames
> * Speed for higher (non-base) layer frames
> * De-blocking (as part of the loopfilter) enabled for:
>   0 = all frames
>   1 = all but frames from the highest temporal layer
>   2 = no frames
>
> Each entry in the list has a threshold in min number of pixels needed
> for settings in the entry to apply.
>
> Example: Two spatial layers (180p, 360p) with three temporal
> layers are configured. Field trial "WebRTC-VP9-PerformanceFlags" set to:
> "min_pixel_count:0|129600,base_layer_speed:5|8,high_layer_speed:7|8,deblock_mode:1|2"
> This translates to:
> S0:
>   - TL0: Speed 5, deblocked
>   - TL1: Speed 8, deblocked
>   - TL2: Speed 8, not deblocked
> S1:
>   - TL0: Speed 7, not deblocked
>   - TL1: Speed 8, not deblocked
>   - TL2: Speed 8, not deblocked

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

See here for instructions on how to get started developing with the native code.
