fdaf7c7b96 nir: add a high precision conversion unorm->float
We'll use this for D32->D24X8 conversion on Intel on Gfx11/Gfx12.0/DG2
(where HW doesn't have fp64 support).

ff2ebdc4d6 nir/format_convert: Promote input to 32-bit before packing integers
If we don't do that and the source is not 32-bit we end up with a
bit_size mismatch when doing the ior operation.

535823682d nir/format_convert: remove unorm bit size assert
Yes, we're losing precision if this assert fails and it's wrong. It's also
necessary to implement GL in a reasonable way on Asahi. Remove the assert that
was recently added and add more comment context on the mess.

Fixes debug build regression on asahi:

   dEQP-GLES3.functional.vertex_arrays.single_attribute.normalize.int.components4_quads1

Fixes: 22f1b04a99 ("nir/format_convert: Assert that UNORM formats are <= 16 bits")

34161d3fda nir: Move most of nir_format_convert to a C file
There's no good reason for this to be header-only besides laziness on my
part when I first wrote a few "small" helpers.  Some of those are pretty
good sized and don't need to be inlined.

Keeping the original copyright since this is just moving code.
