x86/tracing: Introduce a static key for exception tracing
Switching the IDT just for avoiding tracepoints creates a completely
impenetrable macro/inline/ifdef mess.
There is no point in avoiding tracepoints for most of the traps/exceptions.
For the more expensive tracepoints, like pagefaults, this can be handled with
an explicit static key.
Preparatory patch to remove the tracing IDT.
