  WorkQueue should inherit from SerialFunctionDispatcher

Reviewed by Kimmo Kinnunen.

Make WorkQueue inherit from SerialFunctionDispatcher so that it can be
used similarly to RunLoop and WorkerOrWorkletThread.

Needed for this change to compile:
- Export the whole class to get the multiple inheritance to
  work across binaries.
- When exporting WorkQueue, it will export function with OSObjectPtr<dispatch_queue_t>.
  This has different type in Obj-C and in C++. If the type is used in both,
  then there will be unresolved symbol since C++ type is used when creating
  the library (WorkQueue.cpp), as such remove method prototype from WorkQueue
  and have a single WorkQueue constructor taking an enum instead.

Ideally, we would implement only bug 261080, but there are futher issues
getting it done. So to not block other works depending on this change,
we push this version first.
