Make GraphicsContextState use generated serialization
https://bugs.webkit.org/show_bug.cgi?id=262656
rdar://116488200

Reviewed by Ryosuke Niwa.

This patch starts to use generated serialization for GrahpicsContextState instead
of manually specifying ::encode and ::decode. There may have been a performance optimization
in the previous manually written encode, decode. If this is still required, we should generate
this serializer and create an option to replicate the optimization later.
