allow synchronizing user status from OAuth2 login providers (#31572)
This leverages the existing `sync_external_users` cron job to
synchronize the `IsActive` flag on users who use an OAuth2 provider set
to synchronize. This synchronization is done by checking for expired
access tokens, and using the stored refresh token to request a new
access token. If the response back from the OAuth2 provider is the
`invalid_grant` error code, the user is marked as inactive. However, the
user is able to reactivate their account by logging in the web browser
through their OAuth2 flow.

Also changed to support this is that a linked `ExternalLoginUser` is
always created upon a login or signup via OAuth2.

Ideally, we would also refresh permissions from the configured OAuth
provider (e.g., admin, restricted and group mappings) to match the
implementation of LDAP. However, the OAuth library used for this `goth`,
doesn't seem to support issuing a session via refresh tokens. The
interface provides a [`RefreshToken`
method](https://github.com/markbates/goth/blob/master/provider.go#L20),
but the returned `oauth.Token` doesn't implement the `goth.Session` we
would need to call `FetchUser`. Due to specific implementations, we
would need to build a compatibility function for every provider, since
they cast to concrete types (e.g.
[Azure](https://github.com/markbates/goth/blob/master/providers/azureadv2/azureadv2.go#L132))

Implement remote user login source and promotion to regular user
A remote user (UserTypeRemoteUser) is a placeholder that can be
promoted to a regular user (UserTypeIndividual). It represents users
that exist somewhere else. Although the UserTypeRemoteUser already
exists in Forgejo, it is neither used or documented.

A new login type / source (Remote) is introduced and set to be the login type
of remote users.

Type        UserTypeRemoteUser
LogingType  Remote

The association between a remote user and its counterpart in another
environment (for instance another forge) is via the OAuth2 login
source:

LoginName   set to the unique identifier relative to the login source
LoginSource set to the identifier of the remote source

For instance when migrating from GitLab.com, a user can be created as
if it was authenticated using GitLab.com as an OAuth2 authentication
source.

When a user authenticates to Forejo from the same authentication
source and the identifier match, the remote user is promoted to a
regular user. For instance if 43 is the ID of the GitLab.com OAuth2
login source, 88 is the ID of the Remote loging source, and 48323
is the identifier of the foo user:

Type        UserTypeRemoteUser
LogingType  Remote
LoginName   48323
LoginSource 88
Email       (empty)
Name        foo

Will be promoted to the following when the user foo authenticates to
the Forgejo instance using GitLab.com as an OAuth2 provider. All users
with a LoginType of Remote and a LoginName of 48323 are examined. If
the LoginSource has a provider name that matches the provider name of
GitLab.com (usually just "gitlab"), it is a match and can be promoted.

The email is obtained via the OAuth2 provider and the user set to:

Type        UserTypeIndividual
LogingType  OAuth2
LoginName   48323
LoginSource 43
Email       foo@example.com
Name        foo

Note: the Remote login source is an indirection to the actual login
source, i.e. the provider string my be set to a login source that does
not exist yet.

Avoid cycle-redirecting user/login page (#28636)
Fix #28231, and remove some unused code. The `db.HasEngine` doesn't seem
useful because the db engine is always initialized before web route.

Remove GetByBean method because sometimes it's danger when query condition parameter is zero and also introduce new generic methods (#28220)
The function `GetByBean` has an obvious defect that when the fields are
empty values, it will be ignored. Then users will get a wrong result
which is possibly used to make a security problem.

To avoid the possibility, this PR removed function `GetByBean` and all
references.
And some new generic functions have been introduced to be used.

The recommand usage like below.

```go
// if query an object according id
obj, err := db.GetByID[Object](ctx, id)
// query with other conditions
obj, err := db.Get[Object](ctx, builder.Eq{"a": a, "b":b})
```

Fix wrong xorm Delete usage (#27995)
## Bug in Gitea
I ran into this bug when I accidentally used the wrong redirect URL for
the oauth2 provider when using mssql. But the oauth2 provider still got
added.
Most of the time, we use `Delete(&some{id: some.id})` or
`In(condition).Delete(&some{})`, which specify the conditions. But the
function uses `Delete(source)` when `source.Cfg` is a `TEXT` field and
not empty. This will cause xorm `Delete` function not working in mssql.

61ff91f960/models/auth/source.go (L234-L240)

## Reason
Because the `TEXT` field can not be compared in mssql, xorm doesn't
support it according to [this
PR](https://gitea.com/xorm/xorm/pulls/2062)
[related
code](b23798dc98/internal/statements/statement.go (L552-L558))
in xorm
```go
if statement.dialect.URI().DBType == schemas.MSSQL && (col.SQLType.Name == schemas.Text ||
   col.SQLType.IsBlob() || col.SQLType.Name == schemas.TimeStampz) {
   if utils.IsValueZero(fieldValue) {
     continue
   }
   return nil, fmt.Errorf("column %s is a TEXT type with data %#v which cannot be as compare condition", col.Name, fieldValue.Interface())
   }
}
```
When using the `Delete` function in xorm, the non-empty fields will
auto-set as conditions(perhaps some special fields are not?). If `TEXT`
field is not empty, xorm will return an error. I only found this usage
after searching, but maybe there is something I missing.

Refactor Find Sources and fix bug when view a user who belongs to an unactive auth source (#27798)
The steps to reproduce it.

First, create a new oauth2 source.
Then, a user login with this oauth2 source.
Disable the oauth2 source.
Visit users -> settings -> security, 500 will be displayed.
This is because this page only load active Oauth2 sources but not all
Oauth2 sources.

Make every not exist error unwrappable to a fs.ErrNotExist (#20891)
A lot of our code is repeatedly testing if individual errors are
specific types of Not Exist errors. This is repetitative and unnecesary.
`Unwrap() error` provides a common way of labelling an error as a
NotExist error and we can/should use this.

This PR has chosen to use the common `io/fs` errors e.g.
`fs.ErrNotExist` for our errors. This is in some ways not completely
correct as these are not filesystem errors but it seems like a
reasonable thing to do and would allow us to simplify a lot of our code
to `errors.Is(err, fs.ErrNotExist)` instead of
`package.IsErr...NotExist(err)`

I am open to suggestions to use a different base error - perhaps
`models/db.ErrNotExist` if that would be felt to be better.
