Fee estimations currently do NOT (correctly) work for XCMs going over P<>K and P<>E bridges.

They should.

Add XcmPaymentApi and DryRunApi to all runtimes (#380)
7723274 
Adds the paritytech/polkadot-sdk#3607 and
paritytech/polkadot-sdk#3872 to all runtimes.
These APIs work together to allow dry running and estimating execution
and delivery fees for XCMs.

This PR doesn't allow querying the price in assets different than the
relay token for asset hubs. Can be done in a following PR.
Also tracking #388
and #389 for future
improvemens.

Old PR was #359, this
one targets main already updated to Polkadot SDK 1.13.

## Dear reviewer

Although there are a lot of changes, the main one is the addition of the
two aforementioned APIs to all relays and system parachains. The rest of
the files are tests, which all have the same format.
