Don't emit interpolation modifiers on struct fields when outputting GLSL
HLSL (and thus Slang) commonly puts interpolation modifiers like `sample` on the fields of `struct` types used as stage input/output, while GLSL only allows them on global-scope `in` and `out` variables (or ones in blocks).
This change emits a really hacky filtering step to skip over certain modifiers when emitting a declaration. This lets us skip interpolation-mode modifiers when outputting a struct field to GLSL.
Note: this probably gets the `in` or `out` block case wrong...
