Add missing doc files and cleanup nits (#22931)

* nit: Remove useless `$(HasReferenceAssembly)` settings
  - set in /Directory.Build.targets
    - `true` only in `$(IsAspNetCoreApp)` projects
* nit: Remove useless `$(CompileUsingReferenceAssemblies)` settings
  - no current versioning differences between ref/ and src/ assemblies when targeting default TFM
* Add more `$(GenerateDocumentationFile)` settings
  - increases the number of generated doc files, mostly without problems
- !fixup! correct typo in `DebugProxyHost` doc comments
    - was not generating a doc file before
  - remove previous (ineffective) src/Components/Directory.Build.targets setting
  - nit: remove a duplicate `$(GenerateDocumentationFile)` setting
* nit: Remove useless `$(IsPackable)` settings
  - only analyzers and implementation projects are packable by default
    - main use case for explicit setting is projects shipping only in shared framework
  - conditional setting in src/Mvc/Directory.Build.props just subset logic in /Directory.Build.targets
* nit: Remove useless `$(IsProjectReferenceProvider)` settings
  - only implementation projects are providers by default
* nit: Remove useless `$(IsTestAssetProject)` settings
  - set in src/Mvc/test/WebSites/Directory.Build.props
* !fixup! Looks like `InProcessNewShimWebSite` must compile w/o ref/ assemblies
  - restore `$(CompileUsingReferenceAssemblies)` in this one project
