The previous name "pageSize2Mb" defined in
shared/source/helpers/constant.h is inconsistent to other variable,
i.e. pageSize64k.
Furthermore, it's a bit misleading because the page size is defined in
Megabytes (MB), not in Megabits (Mb).

- Given a Base Pointer passed into Get Peer Allocation, then the base
pointer is used in the map of the new allocation to the virtual memory.
- Enables users to use the same pointer for all devices in Peer To Peer.
- Currently unsupported on reserved memory due to mapped and exec
resiedency of Virtual addresses.

previous handle has been freed.
- Release the Ipc Memory Handle when zeMemPutIpcHandle is called.
- Create a new IPC Handle for tracking thru zeMemGetAllocProperties
when ze_external_memory_export_fd_t is used.

- 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.

of the heap vs the end of the heap.

- Added support for mapping any portion of a virtual allocation to a
physical mapping with a lookup function for reserved virtual addresses.
- Added support for multiple mappings linked to the same virtual
reservation.
- Fixed bug with 64 bit addresses on windows with invalid addresses
passed to the user.

properly check for the error and propagate it upwards.

This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().
