dapp staking v3 - Oracle solution

[Dinonard]

Pull Request Summary

Introduces oracle and price-aggregation support for Shibuya runtime.
The overall solution consists of 3 runtime parts:

1. oracle is used to feed native currency values on-chain
2. membership is used to control who is allowed to submit currency values
3. price aggregator is used to aggregate and process submitted currency values

Fourth on-chain step can be considered the existing functionality in dApp staking v3 which re-calculates tier config based on the price.

Changes Overview

• price type has been changed from FixedU64 to FixedU128 for compatibility
  • this is reflected in dapp-staking-v3 and static-price provider pallets, as well as in runtimes
• temporary pallet oracle-benchmarks has been added to address the missing benchmarks functionality in orml-benchmarks pallet
• price-aggregator pallet provides support for price aggregation and calculating moving average
• Astar and Shiden migration logic for static-price-provider has been added
• full solution integration into Shibuya has been done

Check list

• static price provided value migration for all runtimes
• account for weight of OnNewData observer call
• unit tests
• benchmark code
• pallet rustdoc
• revert spec-version update
• integration tests
