Replace `element_type*` handles in HLSLExternalSemaSource with `__hlsl_resource_t` builtin type. The handle used to be defined as `element_type*` which was used by the provisional subscript operator implementation. Now that the handle is `__hlsl_resource_t` the subscript placeholder implementation was updated to add `element_type* e;` field to the resource struct. and return a reference to that. This field is just a temporary workaround until the indexing is implemented properly in llvm/llvm-project#95956, at which point the field will be removed. This seemed like a better solution than disabling many of the existing tests that already use the `[]` operator. One test has to be disabled nevertheless because an error based on interactions of const and template instantiation (potential bug that can be investigated once indexing is implemented the right way). Fixes #84824
