Timothy Flynn b2c112c41a LibWebView+RequestServer: Add a simple test mode for the HTTP disk cache
This mode allows us to test the HTTP disk cache with two mechanisms:

1. If RequestServer is launched with --http-disk-cache-mode=testing, it
   will cache requests with a X-Ladybird-Enable-Disk-Cache header.

2. In test mode, RS will include a X-Ladybird-Disk-Cache-Status response
   header indicating how the response was handled by the cache. There is
   no standard way for a web request to know what happened with respect
   to the disk cache, so this fills that hole for testing.

This mode is not exposed to users.
