Document logger message generator support for primary constructor parameters

[kimsey0]

Describe the issue or suggestion

When dotnet/runtime#101660 merges, we will need to update the relevant parts of the documentation:

1. https://github.com/dotnet/docs/blob/main/docs/core/extensions/logger-message-generator.md needs to be updated to describe the new support and have examples with primary constructors.
2. The new Primary constructor parameter of type Microsoft.Extensions.Logging.ILogger is hidden by a field diagnostic needs to be added to:

   docs/docs/fundamentals/syslib-diagnostics/source-generator-overview.md
