Script loader: remove (PHP based) compression from `load-styles.php` and `load-scripts.php`. WIth the amount of scripts and stylesheets grown a lot over the years, it has become pretty slow and consumes a lot of server resources. Also, most servers are set to compress PHP output anyway. 

Props LucasRolff, azaozz.

Fixes #44815.
See #43308.
