gallivm/nir: add some f16 support

GLSL lowers packhalf2x16 itself, but for SPIRV we don't have that
option.

For packing when NIR lowers it uses f2f16
and for unpack it needs the casting and f2f32

Fixes:
dEQP-VK.glsl.builtin.function.pack_unpack.packhalf2x16*
dEQP-VK.glsl.builtin.function.pack_unpack.unpackhalf2x16*
