Add missing ENABLE_SPIRV_CODEGEN guards for VK_SAMPLED_TEXTURE1D types

The SPIR-V SampledTexture1D commit (71bf911) added case labels for
AR_OBJECT_VK_SAMPLED_TEXTURE1D and AR_OBJECT_VK_SAMPLED_TEXTURE1D_ARRAY
in GetBasicKindType() and DiagnoseRegisterType() without wrapping them
in #ifdef ENABLE_SPIRV_CODEGEN. This causes build failures when SPIRV
codegen is disabled.
