operation will be blocking (lock on config.file)

Extract distinct steps as dedicated functions, especially when the code
is duplicated. This eases analysis of the logic and highlights
differences between callers of a common code.

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.

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.
