sim: enable watchpoint module everywhere

We build & bundle the watchpoint module everywhere, but we don't make
the command line flags available by default.  A few targets opted in,
but most did not.  Just enable the flag for everyone.  Not all targets
will respect the flags (making them nops), but shouldn't be a big deal.
This is how we handle other common modules already.
