This is a no-op change that updates supportsFormat to use the
decoder list before it's reordered by format support. Instead,
supportsFormat iterates through the decoders listed in their
original priority order as specified by the MediaCodecSelector.
The end result is identical.
This is necessary groundwork for a subsequent change that will
indicate in Capabilities whether the decoder that suppports the
format is the primary one as specified by the MediaCodecSelector
(i.e., the one at index=0 in the lists that are now used).
