feature: Relaxed Virtual Memory reservation with pStart

Browse Source 
Related-To: LOCI-3871

- 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.
