507679af - [SYCL] Correct spec about constness of get(properties_tag) member and add respective warning (#17947)

[SYCL] Correct spec about constness of get(properties_tag) member and add respective warning (#17947) Currently some of our docs suggest using `get(properties_tag) {...}` member in kernel functors to specify kernel properties while some suggest using `get(properties_tag) const {...}`. But actually `get(properties_tag) {...}` might not work under certain conditions, so we should update the incorrect docs that they suggest readers to use `get(properties_tag) const {...}` rather than `get(properties_tag) {...}`. Also as @Pennycook suggested, added a diagnostic warning to indicate the user when: -they have declared a `get(properties_tag)` member in the kernel functor AND -they declared `get(properties_tag){...}` rather than `get(properties_tag) const {...}` Updated the tests containing the non-const version of `get(properties_tag)` as well. --------- Signed-off-by: Hu, Peisen <peisen.hu@intel.com>
