Migrate vaadin-text-field to use new base class

[web-padawan]

Motivation

This is a final issue for adding slotted <input> support to vaadin-text-field.

It needs to be done after all the field components using vaadin-text-field are updated to not depend on it.

Part of #84

Proposed solution

1. Add custom element definition to vaadin-text-field base class located in the new package.
2. Move JSDoc annotations from the original element, check that the API docs are generated properly.
3. Move test/typings folder and events type definitions from the original package.
4. Update vaadin-grid-pro-edit-text-field to depend on the new package and adjust its tests, if needed.
5. Optionally, create an extension for the text-field used by vaadin-grid-filter-column.
6. Remove old implementation, keep the import and make it load the new package.
7. Once the new package is published, update Flow counterpart to use it instead of the old one.
