[WIP] Support native token teleportation to ERC-20

[Lohann]

Description

This PR introduces basic support to reserve-based-transfers.

Timechain to external ERC20:

1 - The account calls assets_bridge.teleport_keep_alive(...), and specify the network and amount of tokens to be teleported..
2 - The pallet lock the user's funds in the bridge pot (account managed by the pallet).
3 - A new GMP task is pushed to the queue.

ERC20 to Timechain:

1 - The account calls the ERC20.teleport(..) in the source chain.
2 - The ERC20 contract calls the Gateway Contract, which emits a new message to the timechain RouteI/Network id.
3 - A Chronicle feed that event to the timechain.
4 - The timechain have a special handler for GMP messages which uses timechain network id, this message if valid is handled by pallet-assets-bridge.
5 - The pallet-assets-bridge unlock the tokens and transfer to the specified account.

I have no idea what this is or who told you to do it. this was definitely not discussed in any sprint planning

[dvc94ch]

I have no idea what this is. There is a whole bunch of stuff that is just copied from other crates like the benchmarking, mock, tests. There are no tests. The pallet isn't registered in the runtime. If avneet signs of on it we can merge cc @foravneet , since he commissioned this work he should understand what was done.

God.. no one knows what WIP means? This PR should not be merged yet.

Looks pretty good already. Please ping me on slack for a quick review once it it ready!

[agryaznov]

@FlorianFranzen this is still half done, the other part (with ERC20->TC flow) is here: #1499. Should already work, I'm going to run it locally now

[dvc94ch]

@agryaznov is this still relevant?

@agryaznov is this still relevant?

yes, it is wip

[dvc94ch]

haven't reviewed the asset-bridge or the tests yet

[agryaznov]

integration tests are done; the work on this could be resumed later on
