Editor: Extract block_editor_rest_api_preload method for use with different editor screens

Browse Source 
It is going to be used on the new widgets editor screen. This patch also introduced a new class WP_Block_Editor_Context that is going to be used with revised block editor filters to let extenders to keep their existing behavior. It should also allow to provide more settings through the context class as new screens get introduced like the navigation editor.

Props azaozz, chrisvanpatten, timothyblynjacobs, youknowriad.
Fixes #52920.
