Script Loader: Improve performance of wp_maybe_inline_styles function. 

The `wp_maybe_inline_styles` function is called twice on the average page load. On it's second run however, it did not check to see if the style had already been processed on the first run. This resulted in calling `filesize` and `get_file_contents` unnecessarily, which was bad for performance. Now, the loop around the queued styles, checks to see if the source is set to false, meaning it has already been processed. This change also replaces calls to `filesize` with the core function `wp_filesize`, which improves extensibility. 

Props spacedmonkey, flixos90, peterwilsoncc, joemcgill.
