[SYCL] Fix use_root_sync handling

[HPS-1]

Address issue #16451 , where property use_root_sync is not processed properly. Also revised sycl/test-e2e/GroupAlgorithm/root_group.cpp to not use the deprecated version of parallel_for. (Which was previously blocked by this issue about use_root_sync).

Also here's some explanation for the change in handler.hpp:
This is where the previous code doesn't handle use_root_sync correctly: processLaunchProperties will be called twice, first for the property list returned by the kernel functor's get(properties_tag) method, and then for Props that is passed in as a parameter to parallel_for. Therefore, if the get(properties_tag) method specifies use_root_sync and Props is empty or doesn't contain use_root_sync, what will be done is:

• first, the property list returned by the kernel functor's get(properties_tag) method get processed. And since it contains use_root_sync, setKernelIsCooperative(true) is called;
• then, the property list Props that is passed in as a parameter to parallel_for get processed. And since it doesn't contain use_root_sync (actually for the non-deprecated variants of parallel_for, Props should always be an empty property list), setKernelIsCooperative(**false**) is called
  And thus in the end the MKernelIsCooperative flag will be set to false, while it actually should be true. Revising the code like this solve the problem.

Also MKernelIsCooperative is false by default, so we don't need to worry if setKernelIsCooperative is not called.
