Replace the anti-CSRF token with a [cross origin protection by Go](https://go.dev/doc/go1.25#nethttppkgnethttp) that uses a stateless way of verifying if a request was cross origin or not. This allows is to remove al lot of code and replace it with a few lines of code and we no longer have to hand roll this protection. The new protection uses indicators by the browser itself that indicate if the request is cross-origin, thus we no longer have to take care of ensuring the generated CSRF token is passed back to the server any request by the the browser will have send this indicator.

Since `modules/context` has to depend on `models` and many other
packages, it should be moved from `modules/context` to
`services/context` according to design principles. There is no logic
code change on this PR, only move packages.
- Move `code.gitea.io/gitea/modules/context` to
`code.gitea.io/gitea/services/context`
- Move `code.gitea.io/gitea/modules/contexttest` to
`code.gitea.io/gitea/services/contexttest` because of depending on
context
- Move `code.gitea.io/gitea/modules/upload` to
`code.gitea.io/gitea/services/context/upload` because of depending on
context

The CORS code has been unmaintained for long time, and the behavior is
not correct.
This PR tries to improve it. The key point is written as comment in
code. And add more tests.
