[OpenMP][Clang] Add call to global data sharing stack initialization on the workers side
Summary: The workers also need to initialize the global stack. The call to the initialization function needs to happen after the kernel_init() function is called by the master. This ensures that the per-team data structures of the runtime have been initialized.
