<pre>Simplify decodeLegacySessionState
https://bugs.webkit.org/show_bug.cgi?id=134280
Reviewed by Andreas Kling.
There's no need to use a LegacySessionStateDecoder object with a single member,
just make all functions static and only export a single entry point; decodeLegacySessionState.
No functionality change, just moving code around.
