Upgrade from v1.2 to v1.3 (#87)

Opening PR mostly for visibility - I expect #56 to be finished before,
which would bump everything to v1.2 and then I'll convert this PR to
v1.2 -> v1.3. In its current state, this PR does v1.0 -> v1.3 bump,
although I've only been looking at [v1.2 -> v1.3
changelog](https://github.com/paritytech/polkadot-sdk/releases/tag/polkadot-v1.3.0),
so everything else just compiles.

TODOs left in this PR (which I'd like to address after #56 is finished):
- [x] revert `[cargo upgrade --pinned
--incompatible](https://github.com/polkadot-fellows/runtimes/commit/8df27a586b598d2f783b53cd62b127b8f8ac846a)`
and only leave sdk crates bump;
- [x] rebase on top of #56;
- [x] ensure that remaining PRs from v1.2 -> v1.3 are either not
required for P/K or shall be added later
(paritytech/polkadot-sdk#1344,
paritytech/polkadot-sdk#1333);
- [x] update weights
- [x] ~(maybe worth a separate PR) there's a lot of unused weight files
in this repo - I'd like to remove it~ will do it in a separate PR -
tracked here:
https://github.com/svyatonik/runtimes/tree/remove-unused-weight-files

@liamaharon Can you, please, confirm that the
paritytech/polkadot-sdk#1344 was necessary only
for sdk CI fixes - that PR caught my eye when I was looking at 1.3
CHANGELOG and I was wondering if we need to do the same for Polkadot,
Kusama and system parachains?
