x86/tracing: Build tracepoints only when they are used

The tracepoint macro magic emits code for all tracepoints in a event header
file. That code stays around even if the tracepoint is not used at all. The
linker does not discard it.

Build the various irq_vector tracepoints dependent on the appropriate CONFIG
switches.
