[ImageDecoder] Remove decodeMetadata() in favor of tracks.ready.

Since metadata is always queued automatically, decodeMetadata()
doesn't really do what it says. There's a better web idiom for
this a 'ready' property that's a one-time resolved promise.

Instead of calling decodeMetadata(), clients should just use
decode.tracks.ready.then(...)

Since the last round of breaking changes didn't cause any
issues without a deprecation period, drop decodeMetadata()
without a deprecation period as well.
