[Compat] Skip delay JS on amp pages

```
add_filter( 'powered_cache_delayed_js_skip', function ( $is_delay_skipped ) {
	if ( function_exists( 'is_amp_endpoint' ) && is_amp_endpoint() ) {
		$is_delay_skipped = true;
	}

	return $is_delay_skipped;
} );

```

should do the trick but it's better to bring into the plugin
