The test file naming is inconsistent with naming of the test files for
`sycl_kernel_entry_point`. The `-grammar.cpp` suffix is intended for use in
exercising the syntax of the attribute itself, not what it appertains to. These
tests are more appropriate for `sycl-external-attr.cpp` (or perhaps a
`sycl-external-attr-appertainment.cpp`).
