Editor: Pass `$editor_id` parameter to `tiny_mce_plugins`, `mce_external_plugins`, and `mce_external_languages` filters, for consistency with `teeny_mce_plugins`.

Document the `classic-block` value passed to various editor filters in `wp_tinymce_inline_scripts()`.

Add missing `@since` entries for the existing `$editor_id` parameter in various filters.
