Add test for oversubscribing VRAM in multi process environment that
creates VM, bind large BOs and submit workloads nearly simultaneously.

Previous coverage lacked a scenario combining multi-process bind
with VRAM oversubscription. This generates memory pressure with
multi-process VM Bind activity and concurrent submission, exercising
the bind pipeline under eviction pressure.

v2: Removed helper APIs usage clock_nanosleep and commented code.

v3: Refactored code to smaller functions.
    Added check for available SRAM usage and keep the max process to 20.
