WIP: Migrate from ember-cli-mirage to msw and @mswjs/data

Hmm, since msw is optional in @mswjs/data, I think we could use the webpack's externals trick to just let it get from the global (or other likes window, self, ...).
This would look something like following:

// ember-cli-build.js

...

  return require('@embroider/compat').compatBuild(app, Webpack, {
    extraPublicTrees,
    staticAddonTrees: true,
    staticAddonTestSupportTrees: true,
    staticModifiers: true,
    packagerOptions: {
      webpackConfig: {
        resolve: {
          fallback: {
            // disables `crypto` import warning in `axe-core`
            crypto: false,
            // disables `timers` import warning in `@sinon/fake-timers`
            timers: false,
          },
        },
        externals: ({ request, context }, callback) => {
          if (request == 'msw' && context.includes('@mswjs/data')) {
            return callback(null, request, 'global');
          }
          callback();
        },
      },
    },
  });

I'm not sure if this is more better than the patch approach though 😅
