Vulkan: Pass signal semaphore by value to async thread

Otherwise the signal semaphore is pointing to whatever was passed in
from the main thread.  Currently, this is ok because:

- For external semaphores, ensureNoPendingWork is called
- For surfaces, there's a fixed buffer of semaphores

However, an upcoming change passes a semaphore specified on the stack,
and the thread should not be referencing it.
