WP_Customize_Manager::grant_edit_post_capability_for_changeset() public WP 4.9.0

Re-map edit_post cap for a customize_changeset post to be the same as 'customize' maps.

There is essentially a "meta meta" cap in play here, where edit_post cap maps to the 'customize' meta cap which then maps to 'edit_theme_options'. This is currently required in core for wp_create_post_autosave() because it will call _wp_translate_postdata() which in turn will check if a user can edit_post, but the the caps for the customize_changeset post type are all mapping to the meta capability. This should be able to be removed once #40922 is addressed in core.

{} It's a method of the class: WP_Customize_Manager{}

No Hooks.
