feat(fabric-connector): add getChainInfo, improve getBlock output

- Add new method `getChainInfo` for quering chain information from qscc.
- Add `GetChainInfoEndpointV1` to allow calling `getChainInfo` remotely.
- Refactor `getBlock` so it can return same custom block formats
  as `WatchBlocks`. Default remains the same (full decode block).
  BREAKING CHANGE: It accepts `type` instead of `skipDecode` flag.
- Move common block formatting logic to `cacti-block-formatters.ts`.
- Add tests for new features. Move test common to quering `qscc` to single file
  to increase CI speed.
