sched: remove unused __HAVE_THREAD_FUNCTIONS hook support

__HAVE_THREAD_FUNCTIONS could be defined by architectures wishing to
provide their own task_thread_info(), task_stack_page(),
setup_thread_stack() and end_of_stack() hooks.

Commit cf8e8658100d ("arch: Remove Itanium (IA-64) architecture")
removed the last upstream consumer of __HAVE_THREAD_FUNCTIONS, so change
the remaining !CONFIG_THREAD_INFO_IN_TASK && !__HAVE_THREAD_FUNCTIONS
conditionals to only check for the former case.
