Revert "[media] vpx_video_decoder: dynamically update natural size"

This reverts commit c4948f05.

Reason for revert: Landed too soon (tried to uncheck CQ)

Original change's description:
> [media] vpx_video_decoder: dynamically update natural size
> 
> This changes the behavior implicit resizing of for VP8/9 video. By
> implicit, we mean streams where the dimensions change without a new
> MSE init segment that explicitly describes the new size.
> 
> Prior to this CL, we took whatever resolution was specified by the
> container metadata and scaled any later differing resolution into an
> element of that original size. Many of our decoders worked this way
> before https://chromium-review.googlesource.com/c/chromium/src/+/1026992/,
> which shifted the consensus is to allow dynamic resize. This CL makes
> the libVPX wrapper consistent with those.
> 
> When the size changes we will update videoWidth and videoHeight and
> fire a 'resize' event.
