Have makeResident return error to the caller, instead of always
SUCCESS. This will allow interfaces like zeContextMakeMemoryResident
to fail properly.
Additionally, change the parsing of MemoryOperationsStatus from
ZE_RESULT_ERROR_OUT_OF_HOST_MEMORY to
ZE_RESULT_ERROR_OUT_OF_DEVICE_MEMORY, since when making resources
resident, it is the device running out of memory, instead of the
host.

- 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.

- vm_bind with user fence updates fence value independently for every
VM hence with per-context VMs, every context needs its unique fence
address. This prevents 2 contexts from updating value possibly
writing lower value than the one that was already stored

This patch add new environment variables to control compiler cache.
Works as follow: If persistent cache is set driver check if NEO_CACHE_DIR
is set. If not then driver checks XDG_CACHE_HOME - If exists
then driver create neo_compiler_cache folder, if
not then driver checks HOME directory. If each NEO_CACHE_DIR,
XDG_CACHE_HOME and HOME are not set then compiler cache is disabled.
Current support is for Linux only.
