[Cadl APIView] Stewardship board feedback

[tjprescott]

Implemented in APIView 0.2.0

• Eliminate blank line for decorators (PR Cadl APIView tweaks for Stewardship board #4479)
• Render multi-line strings as """ string literals """ (PR Cadl APIView tweaks for Stewardship board #4479)
• Change style of decorator (blue) to visually identify (PR Cadl APIView tweaks for Stewardship board #4479)
• Don't hide doc decorators. (PR Cadl APIView tweaks for Stewardship board #4479)
• Resolve syntax for rendering properties of anonymous models (comma vs. semicolon) (PR Cadl APIView tweaks for Stewardship board #4479)
• Use documentation toggle features to toggle doc decorator rendering. (PR Cadl APIView tweaks for Stewardship board #4479)

Med Priority

• Line length heuristics. If something is expanded, everything should be expanded.
• Possibly truncate fully-qualified namespace
• Render linter messages as in-line diagnostics
• APIView should somehow block PRs from being merged in GitHub #4375

Low Priority

• Deep linking for models and model properties #6959
• Show only diffs in APIView for easier review of changes #6960
• Ability to drill into a related APIView (i.e. got to definition of something in Azure.Core APIView). This is a feature request of APIView itself.
• Break route links into multiple tokens so that you can navigate from a placeholder to its definition. Ex ("foo/{userId}" where userId is clickable to go to where it is declared).
• Render examples decorator with link to actual example.

Closing this. Certain items are already being tracked in separate issues. Others have existed for nearly 2 years without clamor for change.
