LibWeb: Make Fetch::Infrastructure::{Request,Response,HeaderList} GC'd

Browse source 
This is the way.

On a more serious note, there's no reason to keep adding ref-counted
classes to LibWeb now that the majority of classes is GC'd - it only
adds the risk of discovering some cycle down the line, and forces us to
use handles as we can't visit().
