Previously, we would elide any config change that arrived before the
first frame was decoded, since the accelerated decoder sends one
even if it matches the container config.

Unfortunately, some streams actually do change config before the
first frame (e.g., some RTC streams).  Eliding it leaves the D3D11
decoder configured for the container config.

This CL causes D3D11VideoDecoder to elide the config change, and
prevent re-allocating the D3D11 decoder, only if the config matches
what the container told us.
