Allow to opt out of classic component patching

[SergeAstapov]

opt-in to address #237 until a breaking release is made.

This would allow you to specify:

  let app = new EmberAddon(defaults, {
    cssModules: {
      patchClassicComponent: false
    }
  });

Avoid the deprecation Reopening the Ember.Component super class itself is deprecated if you do not use classic components (or the bindings on classic components, at least).

Thanks to @Turbo87 and @mydea for idea.

Closes #237.

Wonder if @jamescdavis or @dfreeman may release as a new patch version to help upgrading apps and prepare for Ember v4

[SergeAstapov]

This similar to #241 but allows to opt-out of monkey-patching behavior before v2 of this addon gets released

Thank you @SergeAstapov! I'm not sure why CI isn't running here, but I'm aiming to get a minor release out with this today and hopefully a major v2 with the monkeypatching and other old crusty stuff removed entirely soon thereafter!

@dfreeman thank you!
