Semaphores info was stored as an info of event_wait cpu jobs and this
leads to mem leak when the same event_wait job in the same cmd buffer
batch was submitted more than once. As a result,
`dEQP-VK.api.command_buffers.record_simul_use_primary` fails due to a
double-free of sems_info.
In this patch, we no longer use v3dv_event_wait_cpu_job_info to store
semaphores from a submit info, since semaphores is related to a queue
submission and not to the event_wait job type. If we spawn a wait_thread,
we copy semaphores to an auxiliary struct (v3dv_wait_thread_info) that
will be used in wait_thread to get job and semaphores information. When
the spawned thread finishes, it releases the related
v3dv_wait_thread_info and the semaphores copy as well.
Fixes: d5bd18fb ("v3dv: store wait semaphores in event_wait_cpu_job_info")
