feat(build): add an option to disable type checks when running tests

Since editors and IDEs do typechecking and show errors in place,
often there is no benefit to running type checking in our test pipeline.
This PR allows you to disable type checking:

gulp test.unit.js --noTypeChecks

This commit also makes es6 generation optional.

fix(build): removes unnecessary circular dependencies

Closes #5299
