Remove in-tree max-encoded-len and use the new SCALE codec crate instead (#9163)

* Update impl-codec to use new upstream MaxEncodedLen trait

* Adapt crates to use the updated codec crate for `MaxEncodedLen`

* Remove max-encoded-len crate altogether

* Fix test compilation in `pallet-proxy`

* reorganize import (#9186)

* Fix remaining `MaxEncodedLen` imports

* Fix remaining old usages of max-encoded-len crate

* Fix UI test

* Manually depend on new impl-codec to fix Polkadot companion build

* Use newly released primitive-types v0.9.1 that has new codec impls

* Make sure codec deps are up-to-date in crates that use them
