Introduce a heartbeat-based Timeout Detection and Recovery (TDR) mechanism.
The enhancement aims to improve the reliability of device hang detection by
monitoring heartbeat updates.
Each progressing inference will update heartbeat counter allowing driver to
monitor its progression. Limit maximum number of reschedules when heartbeat
indicates progression to 30. This increases the maximum running time of
single inference to about 60 seconds.
The heartbeat mechanism provides a more robust method for detecting device
hangs, potentially reducing false positive recoveries due to long running
inferences.

Add ivpu_fw_sched_mode_select() function that can select scheduling mode
based on HW and FW versions. This prepares for a switch to HWS on
selected platforms.

Implement setting specified buffer ranges as read-only.
In case if specified range is not 64K aligned and 64K contiguous
MMU600 pages are turned on, split 64K mapping to allow 4K granularity
for read-only configuration.

Allocate per-context preemption buffers that are required by HWS.
There are two preemption buffers:
* primary - allocated in user memory range (PIOVA accessible)
* secondary - allocated in shave memory range
