spirv-reader: Support NClamp, NMin, NMax

Also map FClamp, FMin, FMax to WGSL "clamp", "min", and "max".
The behaviour of FClamp, FMin, and FMax doesn't specify
much when operands are NaN.  Map to WGSL functions
which are more prescriptive about results when operands are NaN.

Also add TODOs for the GLSL.std.450 instructions that I had
missed earlier: the interpolate-at instructions
