LOG: [NFC][SYCL] Test use of sycl_kernel_entry_point with null declarations and statements. (#154583)

The `sycl_kernel_entry_point` attribute only appertains to functions.
This change adds missing tests to validate that an appropriate
diagnostic is issued for likely unintentional application of the
attribute to a null declaration or a null statement; perhaps due to an
unintended semicolon.
