Improve xcm asset trapped behaviour when deposit reaches limit

We are introducing a circuit breaker (https://github.com/galacticcouncil/hydration-node/pull/1142) to lock funds if deposit reaches a certain limit.

In case of XCM exchange asset, we use a temporary account for doing the trades on our runtime, but since we don't want to lock any funds on temporary account, we just [return error](https://github.com/galacticcouncil/hydration-node/blob/8645dba338fbe5db52b2c6a072f29f794d169c0b/runtime/adapters/src/xcm_exchange.rs#L84) if the deposit limit reached.

Such error means the asset is trapped on our chain, which is not easy to untrap.

We should consider this and see if we could solve better, or maybe improving our Untrapping process
