The ipi tracepoints are mostly generic, but the tracepoints ipi_raise,
ipi_entry and ipi_exit are only used by arm and arm64. This means these
trace events are wasting memory in all the other architectures that do not
use them.

Add CONFIG_HAVE_EXTRA_IPI_TRACEPOINTS and have arm and arm64 select it to
enable these trace events. The config makes it easy if other architectures
decide to trace these as well.
