[SYCL][NATIVECPU] Implement missing work group collectives in Native CPU libdevice (#15618)

Fixes some issues in Native CPU's libdevice:
* Remove an unused definition of `DefineBroadCastImpl`
* Fix typo in `DefineBroadCastImpl` that lead to incorrect results for
broadcast
* Define  `__spirv_GroupAny`/` __spirv_GroupAll` for work groups
