tp::JobSemaphore struct

A synchronization primitive created after enqueueing a tp::Job through tp::Device::enqueueJob.

It is created in an unsignalled state. Once the corresponding job finishes executing on the device, the semaphore becomes signalled. Both the device and host can wait for the semaphore to become signalled. Its status can also be checked at any point.
