On linux OfflineDumpContextId consists of
32b processId in bits 63:32
32b drmContestId in bits 31:0
Also cache linux implementation of getProcessId since
the value is constant.

It is possible that a module has so many kernels that the 4GB limit of
GPU VA is depleted when each kernel allocates a 64 KB page for its own
ISA. In such case, propagate the ZE_RESULT_ERROR_OUT_OF_DEVICE_MEMORY to
the API caller to indicate the actual problem.
Currently such scenario is not detected, the execution advances a bit
further and the following crashes do not let the user to easily
understand what happened.

- Relaxed the Virtual Memory Reservation to allow pStart and not fail if
the pStart value is not obtained.
- Moves checks on pStart to the user to check and determine if they want
to re-reserve or use the address allocated.
- Changed reserveGpuAddress to use unit64_t type to allow internal
address range structure assignment without cast.

When one process had exported and then opened IPC handle
of memory, then close function was called twice for the
same BO handle. It caused debugBreak() and aborted
an application.
This change allows multiple separate BOs to share one
handle. The last shared handle owner calls close() function.
