SWDEV-132899 - [OCL][GFX10] report number of WGP by default on gfx10 ASICs
	Both HSAIL/SC and LC compilers use WGP mode by default on gfx10 ASICs (i.e., COMPUTE_PGM_RSRC1.WGP_MODE is set to 1 by both compilers) therefore runtime should report number of WGP (i.e., CU/2) on gfx10 ASICs by default.
	The new environment variable (GPU_ENABLE_WGP_MODE = 0)  can be used to force CU mode on LC (i.e., -mcumode option) if it’s needed (HSAIL/SC doesn't have any compiler option for forcing the CU mode)

	Also, using the new environment variable (GPU_ENABLE_WAVE32_MODE) to control the wave32 mode on gfx10+.
