clean up duplicated alloc/free_thread_info
We duplicate alloc/free_thread_info defines on many platforms (the
majority uses __get_free_pages/free_pages). This patch defines common
defines and removes these duplicated defines.
__HAVE_ARCH_THREAD_INFO_ALLOCATOR is introduced for platforms that do
something different.
