This PR contains improved test cases that rely on the governance
location as preparation for AHM to capture the state as it is.
It introduces `execute_as_governance_call`, which can be configured with
various governance location setups instead of the hard-coded
`Location::parent()`.

Additionally, it adds a test for `authorize_upgrade` to all SP testnets.


## TODO
- [x] rewrite all tests using
`RuntimeHelper::<Runtime>::execute_as_governance` (because it is using
hard-coded `Location::parent()`) to use
`RuntimeHelper::<Runtime>::execute_as_governance_call`

## Follow-up
- [ ] add similar test for westend-runtime
- [ ] add test that ensure xcm-executor adds `ClearOrigin` before all
side-effect sent to different chain

- Closes https://github.com/paritytech/license-scanner/issues/44
- Silent because only comments are changed in the crates.

## What's inside

First, we change the file traversal mechanism from shell globbing to
walking through files which happens inside the `license-scanner` - so it
has knowledge about directory structure and can correlate files with
corresponding Cargo manifest.

Next, added `MIT-0` and `Unlicense` to the allowed list of licenses.
`Unlicense` appears only once across {Substrate,Cumulus,Polkadot} - in
`penpal-runtime`.

Finally, updated headers in files that do not match the corresponding
manifest license.

The `query_weight_to_asset_fee` function was trying to convert versions
by using `try_as`, this function [doesn't convert from a versioned to a
concrete
type](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f/polkadot/xcm/src/lib.rs#L131).
This would cause all calls with a lower version to fail.

The correct function to use is the good old
[try_into](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f

/polkadot/xcm/src/lib.rs#L184).
Now those calls work :)
