🐛 Use `401` status code in security classes when credentials are missing
## Warning
This description is partially outdated after changes described in [this comment](https://github.com/fastapi/fastapi/pull/13786#pullrequestreview-3501695067).
## Description
This PR is an attempt to finally solve the issue with security tools returning error responses with status code `403` instead of `401` when credentials are not provided.
## Breaking changes and workaround
These changes can break projects that rely on old behavior.
In order to mitigate this, the `not_authenticated_status_code` is introduced. If set to `403`, it will make it work the same way as it was before changes (return `403` status code).
This option should be treated as a temporary workaround to give developers more time to update Clients to follow the new behavior.
## Changes and reasoning
### APIKeyQuery, APIKeyHeader, APIKeyCookie
* **Standard:**
* These schemes are not covered by standards, but developers usually follow the same rules as for other standards
* **Actions:**
* The default status code for not providing API key was changed from 403 to 401.
* Temporary `not_authenticated_status_code` parameter can be used to revert this behavior back to returning 403 error code without sending `WWW-Authenticate`.
* **Notes:**
* It’s considered to be a good practice to include in `WWW-Authenticate` information needed to understand how the key is supposed to be passed. I implemented default format (`WWW-Authenticate: ApiKey in="...", name="..."` ), but it’s possible to override the template for `WWW-Authenticate` by subclassing and defining the `format_www_authenticate_header_value` method
### HTTP Basic
* **Standard:**
* https://datatracker.ietf.org/doc/html/rfc7617
* **Actions:**
* No needed. This scheme already acts according to the standard in terms of returning 401 status code with `WWW-Authenticate` header on a lack of credentials
* **Notes:**
* `realm` is required according to the RFC, but optional in the current implementation. Fixing this would introduce breaking changes. Considering this is not a problem for people who want to follow the standard, I suggest we leave it as it is.
### HTTP Digest
* **Standard:**
* https://datatracker.ietf.org/doc/html/rfc7616
* **Actions:**
* The default status code for not providing the authorization parameter was changed from 403 to 401.
* `WWW-Authenticate` is just a stub for now (just `WWW-Authenticate: Digest`) (see notes)
* Temporary `not_authenticated_status_code` parameter can be used to revert this behavior back to returning 403 error code without sending `WWW-Authenticate`.
* **Notes:**
* Since the current `HTTPDigest` implementation is just a stub, we can’t follow standards (we don’t generate `nonce`'s, don’t have `realm`, …). I suggest we just change the error status code and add a stub for `WWW-Authenticate` (just `WWW-Authenticate: Digest`). For now `HTTPDigest` can’t be used as it is, so, this is not a problem.
* We can later add full implementation of `Digest` scheme. There have been made several attempts to implement it (#9825, #3071)
* Should we add a note that `HTTPDigest` is just a stub?
### HTTP Bearer, OAuth2 schemes, OIDC
* **Standard:**
* https://datatracker.ietf.org/doc/html/rfc6750
* **Actions:**
* For `OAuth2PasswordBearer` and `OAuth2AuthorizationCodeBearer`: not needed.
* They already return a 401 error code. Implementation is probably not 100% correct (see notes), but considering nobody argued, I think we can leave it as it is for now.
* For `HTTPBearer` and `OpenIdConnect`:
* The default status code for not providing the authorization parameter was changed from 403 to 401. The suggested implementation will be in line with the current implementations of `OAuth2PasswordBearer` and `OAuth2AuthorizationCodeBearer`.
* Temporary `not_authenticated_status_code` parameter added to `HTTPBearer` can be used to revert this behavior back to returning 403 error code without sending `WWW-Authenticate`.
* **Notes:**
* It’s [recommended to return 400 error response](https://datatracker.ietf.org/doc/html/rfc6750#section-3.1) if the parameter is missed or of an unsupported type, but this is not a strict requirement (word SHOULD is used). I suggest we ignore this and follow the approach that is consistent with other schemes.
* The format of `WWW-Authenticate` is not clearly described: It’s said that the value "Bearer" MUST be followed by one or more auth-param values. At the same time, all auth-param attributes are optional. In examples they always add `realm`. Since we don’t have `realm`, I suggest we just skip it and send just `WWW-Authenticate: Bearer`
* We can later improve the `WWW-Authenticate` format by adding `realm` and `scope`
