refactor: migration to polkadot sdk 1.1.0

[i3ima]

This is the tracking PR for the upgrade of polkadot-sdk.
At the moment I can recall of the following issues:

• Some tests and benchmarks don't pass
• Local paths are used in patch sections of workspace-level Cargo.toml (i.e you are forced to have cloned repos of dependencies one directory up)
• Bunch of warnings, some of which can't be fixed by simple cargo fix -- It breaks things (I suspect it's because of procedural macros or other conditional items visibility problem)

Not so issues, but important notes:

• This probably doesn't break anything but should be mentioned anyways. One of the packages that 1.1.0 uses is bandersnatch_vrfs (from ring-vrf ) which contains various important cryptography functions that are used in blocks production. It specifies this dependency via git repository and commit hash (3119f51). At this specific commit hash it causes compiler error because of broken Cargo.toml. So I decided to bump it
• Test test_deposit_collateral_not_enough_balance of pallets/kensetsu/src/tests.rs changes expected error enumeration in which I'm unsure

The lists will be updated as we progress

Currently this PR is not fully ready for review as it's not very clean. Following things will be done next:

• Cleanup rustc & clippy warnings
• Test on predev
