Serve pre-defined files in "public", add "security.txt", add CORS header for ".well-known" (#25974)
Replace #25892

Close  #21942
Close  #25464

Major changes:

1. Serve "robots.txt" and ".well-known/security.txt" in the "public"
custom path
* All files in "public/.well-known" can be served, just like
"public/assets"
3. Add a test for ".well-known/security.txt"
4. Simplify the "FileHandlerFunc" logic, now the paths are consistent so
the code can be simpler
5. Add CORS header for ".well-known" endpoints
6. Add logs to tell users they should move some of their legacy custom
public files

2023/07/19 13:00:37 cmd/web.go:178:serveInstalled() [E] Found legacy public asset "img" in CustomPath. Please move it to /work/gitea/custom/public/assets/img
2023/07/19 13:00:37 cmd/web.go:182:serveInstalled() [E] Found legacy public asset "robots.txt" in CustomPath. Please move it to /work/gitea/custom/public/robots.txt
```
This PR is not breaking.
