nir: add opcodes for 16-bit packing and unpacking

Noitice that we don't need 'split' versions of the 64-bit to / from
16-bit opcodes which we require during pack lowering to implement these
operations. This is because these operations can be expressed as a
collection of 32-bit from / to 16-bit and 64-bit to / from 32-bit
operations, so we don't need new opcodes specifically for them.
