SDK should not trigger generation of .runtimeconfig by compiler #960
Description
Cesium Compiler has an inherent ability to generate .runtimeconfig.json. This ability is implemented mostly for the console compiler use.
Cesium SDK, on the other hand, relies on the .runtimeconfig.json generation introduced by the common .NET SDK (see #946 for details).
In the logs produced when compiling a project via Cesium SDK, there are also traces of the .runtimeconfig.json being generated by the compiler — which is then subsequently ignored.
To reduce the confusion, we should introduce an option for the compiler to skip generation of the .runtimeconfig.json — and this option should be utilized by the SDK, so that no redundant work is done or logged as being done.
The behavior of the current command-line compiler (generate the .runtimeconfig.json by default) should be left as-is.
