Refactor/Standardize Router XSD Schema Attributes

- Add more documentation for schema elements in spring-integration-xml-2.1.xsd
  - Simplify Handling of Channel Resolution (Failures) for Routers
  - Fix PayloadTypeRouterTests
  - Update reference docs, XSD Schemas
  - Rename 'channel-resolution-required' to 'resolution-required'
  - Updated all tests accordingly
