I'm trying to argue that we don't need the extra `_HLSL_AVAILABILITY_6_2` macro
at all. We should be able to use just `_HLSL_16BIT_AVAILABILITY_DEFAULT()`,
since it's always defined for the 16-bit types. For `half` types, you want the
availability attribute only when `__HLSL_ENABLE_16_BIT` is defined, because
otherwise it maps to `float`.
