[SYCL] Deprecate parallel_for and single_task overloads

[HPS-1]

As the title says, added deprecation messages for such overloads in the sycl_ext_oneapi_kernel_properties extension, suggesting users to use single_task/parallel_for overloads provided in the sycl_ext_oneapi_enqueue_functions extension instead. (As these overloads are to be removed later as mentioned in #14785) Also fixed affected test cases by adding the Wno-deprecated-declarations build flag to let them ignore the deprecation warnings.

Also two points to notice:

1. The following overload in the handler class is actually implemented as three function overloads with range<dimensions>... implemented as range<1>..., range<2>... and range<3>... respectively.

   template <typename KernelName, int dimensions, typename PropertyList, typename... Rest>
   void parallel_for(range<dimensions> numWorkItems,
                    PropertyList properties,
                    Rest&&... rest);

2. The following overloads in the queue class appear to have not been implemented so deprecation warnings are not needed here:

  template <typename KernelName, int Dims, typename PropertyList, typename... Rest>
  event parallel_for(range<Dims> numWorkItems,
                     Rest&&... rest);

  template <typename KernelName, int Dims, typename PropertyList, typename... Rest>
  event parallel_for(range<Dims> numWorkItems, event depEvent,
                     PropertyList properties,
                     Rest&&... rest);

  template <typename KernelName, int Dims, typename PropertyList, typename... Rest>
  event parallel_for(range<Dims> numWorkItems,
                     const std::vector<event> &depEvents,
                     PropertyList properties,
                     Rest&&... rest);

  template <typename KernelName, int Dims, typename PropertyList, typename... Rest>
  event parallel_for(nd_range<Dims> executionRange,
                     event depEvent,
                     PropertyList properties,
                     Rest&&... rest);

  template <typename KernelName, int Dims, typename PropertyList, typename... Rest>
  event parallel_for(nd_range<Dims> executionRange,
                     const std::vector<event> &depEvents,
                     PropertyList properties,
                     Rest&&... rest);

SYCL2020 deprecated means that this feature is marked as deprecated in the core SYCL 2020 specification and it will be removed in whatever next version of the core SYCL specification there will be.

However, in this case we are deprecating an overload documented by an extension - it is not related to the SYCL language version and I assume that we want it to be removed way earlier than we drop SYCL 2020 support. Therefore, regular SYCL_DEPRECATED macro should be used

[AlexeySachkov]

Unless we specifically want to test the old API, we shouldn't add this flag but rewrite the test instead. The reason is fear that we can accidentally use even more deprecated APIs in a test, thus making even more work for ourselves in the future PR which removes deprecated overloads.

[AlexeySachkov]

A new test should be added into sycl/test/warnings/ to check that deprecated message is correct and emitted for all overloads
