  Refactor WCLayerUpdateInfo for serialization
https://bugs.webkit.org/show_bug.cgi?id=267968

Reviewed by Chris Dumez.

Modify `WCLayerUpdateInfo` so it's serialization can be generated. The
values to serialize in an instance are controlled by an `OptionSet`.
The generator supports this through `OptionalTupleBit` but it expects
one field per enumeration which is not the case for `WCLayerUpdateInfo`.
Group those fields together into nested structs and sort the fields by
the value of `WCLayerChange` they correspond to.

The actual serialization of `WCLayerUpdateInfo` will come in a separate
change.
