…tch calls When calling `spend` the origin defines the `max_amount` of tokens it is allowed to spend. The problem is that someone can send a `batch(spend, spend)` to circumvent this restriction as we don't check across different calls that the `max_amount` is respected. This pull request fixes this behavior by introducing a so-called dispatch context. This dispatch context is created once per outer most `dispatch` call. For more information see the docs in this pr. The treasury then uses this dispatch context to attach information about already spent funds per `max_amount` (we assume that each origin has a different `max_amount` configured). So, a `batch(spend, spend)` is now checked to stay inside the allowed spending bounds. Fixes: #13167
