This proposal aims to upgrade both Polkadot’s and Statemint’s runtimes to [v9291](https://github.com/paritytech/polkadot/releases/tag/v0.9.29) and [v9290](https://github.com/paritytech/cumulus/releases/tag/parachains-v9290) respectively. For this, the proposal includes a batch call including both runtime upgrade proposals. 

### On Polkadot

This upgrade fixes issues and includes:

**Runtime**

⏳ pending non-critical audit #11813 Low - Proposal: flatten allpallets and similar types

✅ trivial #12032 Low - Contracts: make chain extension state types public

✅ trivial #11670 Low - Replace t::accountid with <t::lookup as staticlookup>::source

✅ trivial #12059 Low - Revert "auto-incremental collectionid"

✅ trivial #12095 ❗️ Medium - Fix nomination pools pending rewards rpc

#12138 Low - Weight v1.5: opaque struct

✅ audited #12145 Low - Uniques: reset approved account after transfer

✅ trivial #12136 Low - Emit events for inter contract calls

✅ audited #12154 Low - [fix] make sure pool metadata is removed on pool dissolve

### On Statemint: 

[C] #1454 Low - [feature] add xcm benchmark weights to statemint

[C] #1551 Low - Update cumulus to latest substrate and polkadot master

Among other things, it includes an update to the XCM weight calculations and prepares for the first Collectives parachain.

Please note this is submitted as an external motion: meaning if/after Council approves, this will also be up for vote by the community to decide on the upgrades.

Make sure to vote at your convenience!


Schedule the currently externally-proposed majority-carries referendum to be tabled
immediately. If there is no externally-proposed referendum currently, or if there is one
but it is not a majority-carries referendum then it fails.

The dispatch of this call must be `FastTrackOrigin`.

- `proposal_hash`: The hash of the current external proposal.
- `voting_period`: The period that is allowed for voting on this proposal.
	Must be always greater than zero.
	For `FastTrackOrigin` must be equal or greater than `FastTrackVotingPeriod`.
- `delay`: The number of block after voting has ended in approval and this should be
  enacted. This doesn't have a minimum amount.

Emits `Started`.

Weight: `O(1)`

Send a batch of dispatch calls.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.
