This change will export the damaged regions (when available) out
to the pipewire client. This change is currently specific to
virtual streams only (where I was able to test the change) and
maintains the current behavior for other screencast stream types.

That means before-update, prepare-paint, before-paint, paint-view, after-paint,
after-update. While yet to be used, it will be used as a transient frame
book keeping object, to maintain object and state that is only valid
during a frame dispatch.

This change fixes the issue where the cursor is always
embedded in the frames even when the client has requested
the cursor information be sent as metadata in the stream.

With the unthrottled input emission, we ended up often getting the
cursor updates long before any damage had been posted, meaning that if
you moved around the mouse pointer where the mouse had a high enough
refresh rate, we'd effectively stall the screen cast stream by only
sending cursor updates and nothing else.
Fix this by scheduling an update when we get a cursor update, then
sending a cursor-only frame after any damage and relayout has been
processed, but only if there is no queued damage that will cause an
actual repaint.

Keep the virtual monitor around if it's being resized. This reduces the
number of unnecessary object rebuilding that happen during monitor
rebuilding.
This changes finalize() vfunc into a dispose() vfunc in the abstract
stream source object implementation, as it needs the abstract stream
source object to close the stream early, so that various signal
listeners get disconnected early.

The new RecordVirtual API creates a virtual monitor, i.e. a region of
the stage that isn't backed by real monitor hardware. It's intended to
be used by e.g. network screens on active sessions, virtual remote
desktop screens when running headless, and scenarios like that.
A major difference between the current Record* API's is that
RecordVirtual relies on PipeWire itself to negotiate the refresh rate
and size, as it can't rely on any existing monitor, for those details.
This also means that the virtual monitor is not created until the stream
negotiation has finished and a virtual monitor resolution has been
determined.
