Devin J. Pohly 33bcd2e4ca Line saver: LISTEN_STATIC macro ...

This parallels the LISTEN macro for statically allocated listeners, and
it allows us to remove almost all of the global wl_listener
declarations.

This also fixes a bug with the axisnotify listener, which was declared
with a compound literal.  At block scope, these have automatic storage
duration [1], so the listener was no longer valid after setup()
returned.  (The option to declare it static explicitly was standardized
in C23, if that ever gains suckless traction.)
