Instead of https://gitlab.winehq.org/wine/wine/-/merge_requests/7815, for https://gitlab.winehq.org/wine/wine/-/merge_requests/7226, this only split the sync ops to a separate vtable and let objects delegate theirs to a separate object.
This starts using a event-like interface for most objects, leaving the decision regarding if/how to split sync themselves / integrate inproc syncs for later.
-- v10: server: Use an event sync for fd objects. server: Introduce a new event sync object. server: Redirect fd-based objects sync to the fd. server: Add an operation to retrieve an object sync. server: Move object grab/release out of (add|remove)_queue. server: Move signal access checks outside of the objects.
