In PHP 7.3, the `compact()` function has been changed to issue an `E_NOTICE` level error if a passed string refers to an unset variable. In previous versions of PHP, this notice was silently skipped. This fixes a few more instances of unset variables in the WordPress admin.
The full RFC can be viewed here: https://wiki.php.net/rfc/compact.

If a meta box is registered with the `__block_editor_compatible_meta_box` set to `false`, it's indicating that it doesn't work in the block editor. If that's the case, we can add a place holder to inform the user that they'll need to use the classic interface to work with this meta box.

- Skips validation where there is no attribute definition, but keeps the attribute value. Previously, the attribute would be omitted from the attributes passed to `render_callback`. Notably, this resolves an issue where `render_callback` cannot receive a block's `align` and `customClassName` attribute values, since these are defined as a client-side filter.
- Validates `null` as a proper value in its own right. Previously, a client implementation of a block could track `{“attribute":null}` as an explicitly empty value, and the server would wrongly initiate defaulting behavior. The new behavior will now only populate a default value if the attribute is not defined at all, including when unset in its being invalid per the attribute schema.

Changes of note:
- Includes the new Annotations API package.
- `wp-polyfill-ecmascript.js` is renamed to `wp-polyfill.js`.
- `strip_dynamic_blocks()` has been removed in favor of `excerpt_remove_blocks()`.
- The PHP block parser is now syncing from the `block-serialization-default-parser` package.
- `do_blocks()` uses the new parser.
- The `do_block` filter has been removed from `do_blocks()`, in favor of a `render_block` filter in `render_block()`.
Also, a little cleanup to `render_block()`. Always normalize `$block['attrs’]` to array in `’render_block’` filter.

The `webpack` and `copy-webpack-plugin` packages have also been updated.
This does not bump the `@wordpress` packages like in [43861] because of conflicts with package versions already installed in `trunk`. The packages will be brought up to date in a subsequent merge.

In [43736], we prevented rendering fields when not present in `?_fields=`. However, because `get_fields_for_response()` is dependent on `get_item_schema()`, any custom fields registered with a null schema would be incorrectly excluded from the response. Because the REST API permits a null schema for `register_rest_field()`, those fields should be included in the available fields for a response.

When 'parent' is set as the path argument name, it gets passed down through to the `create_item()` method and can erroneously reset the 'parent' value on the post itself. Instead, we rename the argument to 'id' and replicate the revision controller's `get_items_permissions_check()` to instead reference 'id'.
Also ensures revision query params (of which there are many) aren't exposed as the query params for autosaves (of which there are two).
