fix: gateway migration et al.

[wischli]

Description

• Fixes Gateway migration from https://github.com/centrifuge/centrifuge-chain/pull/1946
• Removes DMP Queue from runtimes because this was deprecated with Polkadot v1.7.2 (or lower) but we needed to keep the pallet in order to migrate to the new Polkadot SDK Message Queue. This is done now and DMP Queue can be removed safely.
• Removes deprecated common migrations for loans v4 and hold reasons from Polkadot v1.7.2
• Adds migration to remove undecodable ForeignInvestmentInfo v1 storage entries (see Slack for context)

Checklist:

• [x] I have added Rust doc comments to structs, enums, traits and functions
• [x] I have made corresponding changes to the documentation
• [x] I have performed a self-review of my code
• [x] I have added tests that prove my fix is effective or that my feature works

It seems like our try-runtime CI job is broken 🤔
