rcu: Allow short-circuiting of synchronize_rcu_tasks_rude()
There are now architectures for which all deep-idle and entry-exit
functions are properly inlined or marked noinstr. Such architectures do
not need synchronize_rcu_tasks_rude(), or will not once RCU Tasks has
been modified to pay attention to idle tasks. This commit therefore
allows a CONFIG_ARCH_HAS_NOINSTR_MARKINGS Kconfig option to turn
synchronize_rcu_tasks_rude() into a no-op.
To facilitate testing, kernels built by rcutorture scripting will enable
RCU Tasks Trace even on systems that do not need it.
