be93e38152 aco/vn: remove instruction hash templates
This reuses the instruction data size helper used for creating instruction.
It also removes the hashing of the aco::spans used for operands and definitions,
which was redundant with hash finalization.

80652de67b aco/ra: use SDWA for 16bit instructions when the second byte is blocked
Found by inspection, I think this can happen with pack_32_4x8(f2u8(a@16)),
which will use v_cvt_u16_f16 (a 16bit instruction) with a v1b definition.
