Pokladot sdk backport to staging (#2746)

* Bump to `polkadot-sdk` master `ebe2aad6`

* align with others

* Backport xcm version stuff from `polkadot-sdk`

* Backport Slava's commit from `polkadot-sdk`

* Workspace clippy as `polkadot-sdk` does

* Make submodules use workspace lints

* Add Bridges clippy addons to workspace lints

* Looks like we dont need extra clippy addons anymore?
