	SWDEV-77522 - fix for erroneous CL_DEVICE_VERSION reporting by RT for HSAIL.

	[Synopsis]
	On a CI+ Device (KV, for example) if GPU_HSAIL_ENABLE=1 (which forcing HSAIL) CL_DEVICE_VERSION reported by RT is 1.2; if GPU_HSAIL_ENABLE=0 (default for now), then CL_DEVICE_VERSION = 2.0. It looks like this behaviour exists since then HSAIL was based on EDG, which supports only OpenCL 1.2. Now when HSAIL is based on Clang and supports OpenCL 2.0, there is no need in lowering CL Device Version at all for all CI+ devices nomatter the default path is (HSAIL or AMDIL).

	This bug is a stopper for enabling HSAIL by default for OpenCL 1.2. Actually the problem occurs with OpenCL 2.0 programs when forcing them on HSAIL but with -cl-std=CL2.0 option, since they couldn't be executed on 1.2 device.

	Testing: Pre check-in.
