big cleanup

Lots of code here isn't needed anymore because we dropped support for the last ember versions that needed moduleApiPolyfill, which means we can always use babel-plugin-ember-template-compilation, which is smart enough to handle its own parallelizability.

-## Tagged Template Usage / Migrating from `htmlbars-inline-precompile`
-
-Starting with version 4.0, this addon now includes the testing helper from [ember-cli-htmlbars-inline-precompile](https://github.com/ember-cli/ember-cli-htmlbars-inline-precompile)
-
-This will require an update to the imports of the `hbs` helper in your tests:
-
-Prior syntax:
-
-```
-import hbs from 'htmlbars-inline-precompile';
-
-...
-
-await render(hbs`
-  <MyComponent />
-`);
-```
-
-New syntax:
-
-```
-import { hbs } from 'ember-cli-htmlbars';
-
-...
-
-await render(hbs`
-  <MyComponent />
-`);
-```
-
-There is a [codemod](https://github.com/ember-codemods/ember-cli-htmlbars-inline-precompile-codemod) available to automate this change.
