Subject: [PATCH] Include commit SHA in `[AssemblyInformationalVersion]` value
 (#22649)

* Add `[AssemblyMetadata("CommitHash", ...)]` to all C# assemblies
- see dotnet/arcade#5866 discussion
- provide the commit SHA though not in usual `[AssemblyInformationalVersion]` format

* Include `[AssemblyMetadata("Serviceable", "true")]` too
- see dotnet/arcade#1526
