SWDEV-83467 - [SPIRV] Add support of SPIRV to CPU
	Modifying runtime and compile time to allow SPIRV binaries to run on CPU since it only runs on HSAIL GPU
	Added changes to allow conversion of CPU's llvmBinaryIsSpir boolean into compiler library's oclElfSections enum
	Cpuprogram.cpp's llvmBinaryIsSpir flag renamed to elfSectionType will now support LLVMIR, SPIR, and SPIRV
	Added SPIRV to compiler lib's elf as new oclElfSections enum
	cpuprogram.cpp changes also made to gpuprogram.cpp's NullProgram to allow compilation
