- When the database returns an error about the SQL query, the error is
logged but not the SQL query and arguments, which is just as valuable as
the vague deeply hidden documented error that the database returns.
It's possible to log the SQL query by logging **all** SQL queries. For
bigger instances such as Codeberg, this is not a viable option.
- Adds a new hook, enabled by default, to log SQL queries with their
arguments and the error returned by the database when the database
returns an error.
- This likely needs some fine tuning in the future to decide when to
enable this, as the error is already logged and if people have the
`[database].LOG_SQL` option enabled, the SQL would be logged twice. But
given that it's an rare occurence for SQL queries to error, it's fine to
leave that as-is.

- Databases are one of the most important parts of Forgejo, every
interaction with Forgejo uses the database in one way or another.
Therefore, it is important to maintain the database and recognize when
Forgejo is not doing well with the database. Forgejo already has the
option to log *every* SQL query along with its execution time, but
monitoring becomes impractical for larger instances and takes up
unnecessary storage in the logs.
- Add a QoL enhancement that allows instance administrators to specify a
threshold value beyond which query execution time is logged as a warning
in the xorm logger. The default value is a conservative five seconds to
avoid this becoming a source of spam in the logs.
- The use case for this patch is that with an instance the size of Codeberg, monitoring SQL logs is not very fruitful and most of them are uninteresting. Recently, in the context of persistent deadlock issues (https://codeberg.org/forgejo/forgejo/issues/220), I have noticed that certain queries hold locks on tables like comment and issue for several seconds. This patch helps to identify which queries these are and when they happen.
- Added unit test.

The xorm `Sync2` has already been deprecated in favor of `Sync`,
so let's do the same inside the Gitea codebase.
Command used to replace everything:
```sh
for i in $(ag Sync2 --files-with-matches); do vim $i -c ':%sno/Sync2/Sync/g' -c ':wq'; done
```
Some dbs require that all tables have primary keys, see
- #16802
- #21086
We can add a test to keep it from being broken again.
Edit:
~Added missing primary key for `ForeignReference`~ Dropped the
`ForeignReference` table to satisfy the check, so it closes #21086.
More context can be found in comments.

A testing cleanup.
This pull request replaces `os.MkdirTemp` with `t.TempDir`. We can use the `T.TempDir` function from the `testing` package to create temporary directory. The directory created by `T.TempDir` is automatically removed when the test and all its subtests complete.
This saves us at least 2 lines (error check, and cleanup) on every instance, or in some cases adds cleanup that we forgot.
Reference: https://pkg.go.dev/testing#T.TempDir
```go
func TestFoo(t *testing.T) {
// before
tmpDir, err := os.MkdirTemp("", "")
require.NoError(t, err)
defer os.RemoveAll(tmpDir)
// now
tmpDir := t.TempDir()
}
```
