A Reset control on a host page (meshcore-solo-site's RESET button,
mesh.html's own Reset buttons) re-invokes the MODULARIZE factory for the
same simInstanceTag to simulate a device restart, since board.reboot()
just exit()s the wasm process (inert / freezes the tab under
-sEXIT_RUNTIME=0). Nothing ever tore down the OLD instance's own
emscripten_set_main_loop() callback, so it keeps ticking forever after
being "replaced" -- and keeps drawing onto the same simInstanceTag-keyed
<canvas> the new instance draws onto too. Two visible symptoms this
caused on meshcore-solo-site: flicker/reversion after resetting the same
device more than once (multiple orphaned instances competing for one
canvas), and -- together with the HomeScreen::poll() fix in 5fbfd7c5 --
would have still left a residual single-old-instance repaint race even
after that fix alone.
sim_stop_main_loop() wraps emscripten_cancel_main_loop() so a host page
can explicitly stop the OLD Module reference right before discarding it.
