Support codec and container switching with MSE using SourceBuffer.changeType()

This change adds the SourceBuffer.changeType() method to improve cross-codec or cross-bytestream transitions during playback with Media Source Extensions.


We are incubating this feature via the WICG, with goal of eventually working with WebPlatformWG to get the result of WICG incubation as part of the next version of the Media Source Extensions API (MSE).
