* Enable `/warnAsError` in Windows builds
  - already enabled in non-Windows builds because override existed only in build.ps1
* Allow some warnings related to closed issues
  - common `<NoWarn>$(NoWarn);CS1591</NoWarn>` case unchanged
    - /Directory.Build.props ensures that warning remains a warning but doesn't hide it
* !fixup! Root build.sh _does_ disable warnings as errors
  - variable eng/common/tools.sh uses named `warn_as_error`

* Add test for assembly versions

* Add test for framework list

* Add some hardcoded lists for sharedfx and targeting pack content

HTTP/2 over TLS is not compatible with Windows versions strictly older than Windows 10 or Windows Server 2016. Update kestrel to:
- Downgrade to HTTP/1.1 when Http1AndHttp2 is configured.
- Throw NotSupportedException when Http2 is configured.
- Allow HTTP/2 over TLS to be enabled if AppContext switch Microsoft.AspNetCore.Server.Kestrel.EnableWindows81Http2 is set. This allows users who have configured cipher suites on Windows 8.1 and Windows Server 2012 R2 to continue using HTTP/2 over TLS.

* Remove tests from official builds
  - #22787

nit: _add_ dependency on Windows ARM64 build when publishing to the BAR
    - not a major problem because this particular build rarely if ever fails
    - the existence of the correct manifests is much more important

* Address nit: `Windows_64_build` -> `Windows_arm64_build`

* 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

* Fix path for artifacts in SignalR tests

* Update syntax to match repo convention

- Enabled Helix for:
    - `Microsoft.AspNetCore.Mvc.Razor.Extensions.Test`
    - `Microsoft.AspNetCore.Mvc.Razor.Extensions.Version1_X.Test`
    - `Microsoft.AspNetCore.Mvc.Razor.Extensions.Version2_X.Test`
- These tests depended on our MVC shim project's deps.json's to exist in the test bin directory during publish. Therefore added an additional target copy over those assets at publish time.
- There were some tests that were relying on source positions from a string to match a runtime generated source position. In Helix dll's are built on Windows (string's get compiled with \r\n) and then deployed to potentially non-Windows boxes resulting in mismatches of expectations. To address this I changed the test that had this dependency to dynamically generate the input string.
- Our common language test project used to rely on test files being on disk. At some point in the past those test files started being embedded in the assembly but we maintained directory checking logic to ensure various directories existed on disk (no longe required). Changed the logic to not enforce directories to be on disk (they aren't in Helix) and instead only rely on the embedded TestFiles.

Copying @anurse's guidance from a [gist](https://gist.github.com/anurse/af1859663ac91c6cf69c820cebe92303) into the repo so it can be updated by the team.

Adding Azure Table Storage and CosmosDB SQL providers to the list.

This test makes it clear root domains are not included in CORS subdomain wildcards
