Jonas Ådahl 688280f82d remote-desktop/session: Handle unable to transform coordinate gracefully
There may be a race between the ability to turn stream relative input
coordinates and turning them into screen coordinates, due to the future
scenario where the entity backing a stream is created and managed ad-hoc
depending on PipeWire stream negotiations.

When an input event is sent during this time, drop it.
