Added Get method to receive component implementation by its name

#2998

Thank you for this PR. There are a couple of things we might change before getting this merged:

1. I am not sure that adding a new helper method to get the component implementations is a good idea. This feature might be a niche, we can make the COMPONENTS_IMPLEMENTATION_MAP again available here instead
2. Please add unit tests for all the changes applied to the source code
3. The typescript interfaces should be updated accordingly

I've just added the necessary globals, but it would be best if you could check this discussion: #3001.
