Fail build program in shared system USM + stateful access case

Browse Source 
Signed-off-by: Kamil Kopryk <kamil.kopryk@intel.com>
Related-To: NEO-6075

After this change driver will fail clBuildProgram/zeModuleCreate api calls
whenever stateful access is discovered and device has shared system usm caps
enabled.This is required since in this case allocation greater than 4GB
will not work.
If user still wants to use stateful addressing mode,
-cl-opt-smaller-than-4GB-buffers-only / -ze-opt-smaller-than-4GB-buffers-only
build option should be passed as build option, but then user can not use
buffers greater than 4GB.
