1. glsl-in: Texture builtins fixes …

   This one grew out of hand quick. Initially it was just replacing the bit
   loops with a function driving the declarations to make the code sharing
   better and support different scalar kinds.
   
   Now it includes a lot of fixes:
   - `textureSize` now also returns the array layers as the last component
     on the return (only for arrayed textures)
   - `textureSize` now supports multisampled textures
   - the `texture` family of functions now consumes a `vec3` coordinate
     vector for all 1D shadow textures
   - Shadow textures can use the bias version of `texture` functions
     (temporarily disabled since naga doesn't support it)
   - 3D textures can be used in `textureProj`
   - `sampler2DArrayShadow` can't be used in `textureLod` or in `texture` with bias
   - Cube textures cannot be used with offsets
   
   Updates the tests to cover all functions
