shader_ir/decode: Fix half float pre-operations and remove MetaHalfArithmetic

Browse Source 
Operations done before the main half float operation (like HAdd) were
managing a packed value instead of the unpacked one. Adding an unpacked
operation allows us to drop the per-operand MetaHalfArithmetic entry,
simplifying the code overall.
