Activating "debug" mode for Stimulus for dev builds

Hi!

Well... this was such an easy win, we should have done it awhile ago :).

For a "dev" build, this activates Stimulus's debug mode, which outputs a lot of information to the log. Here is an example of a page with a single controller... and then after I activate an action on that controller:

When running `yarn encore production` (or `npm run encore production`), debug mode will be disabled. Heck, Weback is SO cool that, when building for production, the entire new `if` statement is omitted (i.e. this adds 0 extra bytes to production builds).
