Changes

Drop the XcmRouter.fee_per_second field and add the 2 following new ones

pub transact_weight_at_most: Weight,
pub overall_weight: Weight,
pub fee_amount: u128,

That way we have complete control over those two values being passed down to XcmTransactor, instead of storing values which then have harcoded calculations in the runtime which we can't change without a runtime upgrade.

And adjust the integration tests to use reasonable amounts and verify
the fees being charged.

We have to keep the max_gas_limit since we needed that for the encoded evm call function. We could derive that from the transact max weight but then we are again stucking ourselves with hardcoded logic.

@cdamian @wischli @mustermeiszer this should be ready now. The only thing we need to discuss is migrations, which would only be needed for Algol. do we want to do that? 🙃

Thanks for removing this, it was a left-over from the time we had init logic in the router IIRC.

My artifact. just thought it is still valid to test whether it works if global info is not set. But is implicitly anyways tested ^^
