ECR #333753 - HSA RT/Compiler Lib/Performance: Elimination of HSAIL text usage in RT

	Extracting HSAIL from the binary and parsing it for the kernel names in RT were replaced with aclQueryInfo call for RT_KERNEL_NAMES.
	Kernel names are obtained now from the corresponding metadata symbols names, which are already presented in BIF at kernel finalization stage.

	Side effect: performance improvement

	Next Step: Performance: elimination of BRIG disassembling to HSAIL as obligatory stage in Compiler Lib (previously was needed only by RT).

	Testing: pre check-in, ocl conformnace 2.0 (basic, api, compiler, workgroups, device_execution)

	Reviewers: Stanislav Mekhanoshin, German Andryeyev, Brian Sumner
