Add --file-based option for relevant templates #51726
Description
We should consider updating the following dotnet new templates with a new --file-based option that creates them as file-based apps. This option would be configured to not be shown in Visual Studio as it doesn't support file-based apps.
consoleweb(empty web)webapiaot(web API w/ native AOT)
These templates are simple enough that it's reasonable to offer a file-based apps option for them.
The console template is of course super simple (one appname.cs file, one line of code), but the web templates would include an appname.run.json file and appname.settings.json/appname.settings.Development.json files which is handy.
