Remove all PHP code from the Gutenberg plugin

[danielbachhuber]

After WP 5.0 is released and the Gutenberg plugin's minimum-supported version is 5.0, we should remove all PHP code from the plugin. This includes, but isn't limited to:

• WP_Block_Type_Registry, WP_Block_Type
• WP_REST_Autosaves_Controller
• WP_REST_Block_Renderer_Controller, WP_REST_Blocks_Controller
• WP_REST_Post_Search_Handler, WP_REST_Search_Controller, WP_REST_Search_Handler.
• lib/rest-api.php

We need to keep this PHP code in Gutenberg in the interim, so it's still possible to install Gutenberg on a 4.9.x installation.

Fatal error: Cannot declare class WP_REST_Search_Controller`
This forced me to remove Gutenberg , wp-admin couldn't be accessed

[cristianozanca]

Fatal error: Cannot declare class WP_REST_Search_Controller, because the name is already in use in /var/www/mywordpress/wp-content/plugins/gutenberg/lib/class-wp-rest-search-controller.php on line 0

@altrovideo Are you running the 5.0 branch? If so, you'll need to wait for Gutenberg 4.1 to land as it has the code that conditionally loads these classes #10531

Yes I'm running WP 5.0 nightly build, I'll wait for Gutenberg 4.1, Thanks @danielbachhuber

Closing in favor of #11015
