feat: chain-capabilities.js constants

- adds `IcqEnabled` and `PfmEnabled` constants to support `CosmosChainInfo`
- this data is not available via a well-known registry like cosmos/chain-registry,
  but necessary for the Orchestration API
- exports `withChainCapabilities` helper so consumers can include this data with fetched-chain-info.js
