-This can be achieved by passing CL_QUEUE_THROTTLE_LOW_KHR as throttle hint
to command queue.
- This gives much better control about the granularity of this feature
instead of triggering this for the whole context user may still have
power saving mode queues.

- When queue is created with throttle hint low it should be power conservative
- With this change whenever queues with low throttle setting requests wait
for GPU completion, such wait will be handled in power conservative manner.
- Whenever GPU is not completed, waiting thread will be put to sleep and will
for GPU completion that triggers the wake up interrupt.

- It allows to easily turn ON the power saving mode for the driver.
- In that mode, whenever GPU is not ready it will put current thread to sleep,
thread is resumed when GPU completes.
- PowerSaving mode reduces CPU utilization on blocking calls, while increasing
completion latencies.

- in VA sharing scenarios driver needs to be as power efficient as possible
- Added new mode to KMD notify helper called maxPowerSavingMode
- in this mode, whenever GPU is not busy, driver will choose non busy wait
path.

- This is to improve battery usage while waiting in busy loop on CPU
- New Kmd Notify helper to maintain dynamic parameters
- Ask OS about battery status on longer waits
- Pick different timeout when using battery and optimization is disabled

- Decission about timeout enabling and value moved out of CSR
- Timeout multiplier is no longer Linux specific

- Measure time between wait calls. If delay is exeeded use QuickKmdSleep
- Kmd Notify helper functions
- Refactor overriding from debug variables
- Refactor Kmd Notify tests
