Ignacio Palacios cfc4050d6b Improve Penpal runtime + emulated tests (#3543 )

Issues addressed in this PR:
- Improve *Penpal* runtime:
- Properly handled received assets. Previously, it treated `(1, Here)`
as the local native currency, whereas it should be treated as a
`ForeignAsset`. This wasn't a great example of standard Parachain
behaviour, as no Parachain treats the system asset as the local
currency.
- Remove `AllowExplicitUnpaidExecutionFrom` the system. Again, this
wasn't a great example of standard Parachain behaviour.
- Move duplicated
`ForeignAssetFeeAsExistentialDepositMultiplierFeeCharger` to
`assets_common` crate.
- Improve emulated tests:
  - Update *Penpal* tests to new runtime.
- To simplify tests, register the reserve transferred, teleported, and
system assets in *Penpal* and *AssetHub* genesis. This saves us from
having to create the assets repeatedly for each test
- Add missing test case:
`reserve_transfer_assets_from_para_to_system_para`.
  - Cleanup.
- Prevent integration tests crates imports from being re-exported, as
they were polluting the `polkadot-sdk` docs.

There is still a test case missing for reserve transfers:
- Reserve transfer of system asset from *Parachain* to *Parachain*
trough *AssetHub*.
- This is not yet possible with `pallet-xcm` due to the reasons
explained in https://github.com/paritytech/polkadot-sdk/pull/3339

Assets Parachain

Implementation of Asset Hub, a blockchain to support generic assets in the Polkadot and Kusama networks. Asset Hub was formerly known as "Statemint".

Asset Hub allows users to:

Deploy promise-backed assets, both fungible and non-fungible, with a DOT/KSM deposit.
Set admin roles to manage assets and asset classes.
Register assets as "self-sufficient" if the Relay Chain agrees, i.e. gain the ability for an asset to justify the existence of accounts sans DOT/KSM.
Pay transaction fees using sufficient assets.
Transfer (and approve transfer) assets.
Interact with the chain via its transactional API or XCM.

Asset Hub must stay fully aligned with the Relay Chain it is connected to. As such, it will accept the Relay Chain's governance origins as its own.

See the article on Asset Hub as common good parachain for a higher level description.

Wallets, custodians, etc. should see the Polkadot Wiki's Integration Guide for details about support.
