Auto savestate (and its optional thumbnail) is generated on core unload (quit, netplay start, etc). This ends up using the task-queue, which in many cases deadlocks and/or causes a crash due to its asynchronous nature. Given that this is a state that must be generated before quiting or reloading the core, it makes no sense to use the task queue, it should be a synchronous job like for instance SRAM saving. This should fix #15248 (tested by @schmurtzm)
