Cannot compile OneTBB 2022.3.0 without RTTI

[jdumas]

Hi,

Due to this line:

oneTBB/include/oneapi/tbb/task_group.h

Line 672 in 0cd32ab

task_handle_task* curr_th_task = dynamic_cast<task_handle_task*>(curr_task);

OneTBB can no longer be compiled without RTTI enabled. This wasn't an issue in OneTBB 2022.2.0, but it is with 2022.3.0. Since __TBB_PREVIEW_TASK_GROUP_EXTENSIONS is enabled by __TBB_BUILD, there is no way to "opt-out" of this feature for now.
