When running gitea for the first time, the stylesheets for the
installation page are broken since the middleware that statically serves
stylesheets does not get executed by chi. This is because if no handlers
are registered in chi, it will drop all middleware.
This commit introduces a "dummy" handler to deal with that quirk.
Closes#13725
Thanks: Lunny Xiao <xiaolunwen@gmail.com> for finding the quirk

This enabled HTTP time-based cache for storage assets, primarily
avatars. I have not observed If-Modified-Since from browsers during
tests but I guess it's good to support regardless.
It introduces a new generic httpcache module that can handle both
time-based and etag-based caching.
Additionally, manifest.json and robots.txt are now also cachable.
* Use mount but not register for chi routes
* Fix test
* Fix test
* Fix test
* Fix comment
* turn back unnecessary change
* Remove the timout middleware since some operations may spend much time.
