Currently `DeriveKey` is called every time that a secret must be encoded/decoded. Since this function is deterministic, its result can be cached to allow a 250x speedup (the original took less than half a microsecond, so this more of a micro-optimization...).

## Other changes
- Since the keys can be constructed once, it simplifies a bit the callsites (`keying.TOTP.Encrypt(...)` instead of `keying.DeriveKey(keying.ContextTOTP).Encrypt(...)`)
- All `Encrypt`/`Decrypt` calls will panic forever if called before `Init` has been called (current it panics as long as `Init` has not been called)
- Calling `Init` twice with different keys will trigger a panic (currently racy)
- Calling `Decrypt` with a short ciphertext does not panic anymore (like when calling with long-enough garbage)

- Follow up of forgejo/forgejo!5041, forgejo/forgejo!6074, forgejo/forgejo!8692
- The `task` table contains three secrets: clone address (with credentials), auth password and auth token. These secrets are stored for migrating repositories (also the only usage of this table, although it allows for more usages).
- Use `keying` to safely store these secrets and bound them to the table, column, row id and JSON field name.
- The migration isn't spectacular but does closely follow what we learned in the previous two migrations: use a transaction and delete records when you can't decrypt them. We also learned about `db.Iterate` not being happy when updating records but it has since been fixed.

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.
