asm: avx2 interp_8tap_hv_pp for 8bpp

Removing x265_interp_8tap_hv_pp_16x16_avx2 seperate asm code, since its giving same performnace as calling interp_8tap_hv_pp_cpu C function(which calls luma_hps and luma_vsp asm functions individually)

Including ALL_LUMA_PU_T for luma_hvpp which calls interp_8tap_hv_pp_cpu C function.
ALL_LUMA_PU_T has declared all sizes except 4x4, hence including luma_hvpp[4x4] separately.
