Update to use new stdlib APIs with witness filtering

[dr-orlovsky]

Part of the epic:

• Witness filtering with refactored state management workflow rgb-std#241
• Support new witness filtering rgb#227
• Update to use new stdlib APIs with witness filtering rgb-schemata#45
• Move non-consensus data types to stdlib; better separate commitments and logic validation rgb-core#263
