[SPIR-V] Remove unnecessary cases for SampledTexture that are breaking builds (#8375)

Part of #7979

It's breaking the build because the SampledTexture types aren't wrapped
around `#ifdef ENABLE_SPIRV_CODEGEN`.

In fact, these cases aren't needed and should be removed.

`GetBasicKindType` maps `ArBasicKind` values to Clang QualType objects.
SampledTexture wrappers are not introduced through that mapping table,
so it shouldn't be added here.
