* Remove font management code
Since the Font Management page is on its way out via deprecation, we
should remove the js code related to it.
* lint: Add missing dependency to useSelect
* Remove php files
* remove references to index.js and php files
* remove font library react app
* remove tests & data
* remove demo text input
* Removed some unused resources
* Returned the font management portion still needed
* removed unused utility functions and their unit tests (leaving a sample unit test in its place rather than dismantling the unit tests
* Returned create-panel to pre-fixed days

This depreciation warning is really driving me crazy:
```
PHP Deprecated: Creation of dynamic property Create_Block_Theme::$loader is deprecated in ... class-create-block-theme.php on line 49
```
This is just a quick fix.
* Refactor the plugin using boilerplate plugin project and attempting to better encapsulate logic.
* Allow themes to be exported in addition to creation of child themes and cloned themes.
* Disabled the plugin when a block theme is not activated.
* Exclude templates from PARENT themes when creating or exporting a child theme.
