Tools to improve H5P content integration in Moodle 3.8

This project is intended to provide for Moodle one of the open-source solutions (H5P) to allow teachers to easily use engaging content in their activities.

For Moodle 3.8 (this epic) we are integrating the following H5P functionality:

• H5P renderer
• Ability to add H5P content through an Atto editor button everywhere Atto can be used
• Filter to automatically convert h5p urls to embed code

This functionality will be able to be used in conjunction with the existing [H5P plugin|https://moodle.org/plugins/mod_hvp]

For Moodle 3.9 we are planning to integrate the full functionality of the existing H5P plugin:

• Integrate H5P content types as Moodle activities (but with improved integration and user experience)
• Connect the H5P content types to gradebook and activity completion
