Modify USM device allocation information returned by clGetDeviceInfo

According to USM extension spec, clDeviceMemAllocINTEL will return
NULL and CL_INVALID_OPERATION status if the device has property
CL_DEVICE_DEVICE_MEM_CAPABILITIES_INTEL equal to 0. Before, the
runtime always return 1 for device allocation capabilities as all
legacy devices support device allocations. This is no longer true
in IP Authoring flow.
