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.

Subject: [PATCH] [NFC][SYCL] Test use of sycl_kernel_entry_point with null
declarations and statements.
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.
