core: move GetPrice from `core` to `interop` We have additional logic for getting BaseExecFee policy value. This logic should be moved to interop context instead of being in Policer, because Policer is just an interface over Policy contract. After moving this logic to interop context, we need to use it to define BaseExecFee instead of (Policer).BaseExecFee. Thus, moving (Blockchain).GetPrice to (Context).GetPrice is necessary. 2021-02-05 08:25:22 +00:00			`package interop`

interop: fetch baseExecFee once and keep it in the Context It never changes during single execution, so we can cache it and avoid going to Policer via Chain for every instruction. 2021-08-11 12:42:23 +00:00			`return fee.Opcode(ic.baseExecFee, op)`
