Query delivery fees v2

[franciscoaguirre]

Adds an asset_id parameter to XcmPaymentApi.query_delivery_fees so fees can be estimated in assets other than the native one.

Fixes #7061

Continuation of #8297

TODO

• Add parameter to runtime API
• Add parameter to pallet-xcm helper
• Test querying delivery fee in an asset other than native
