Support #define in Fsharp #2918

Is your feature request related to a problem? Please describe. I'd like to use FSharp assert function in interactive notebook, which requires DEBUG compiler option to be enabled. However by default it's not enabled. C# provides #define statement to accomplish the goal, while F# doesn't

Describe the solution you'd like I'd like to use #define DEBUG in F# as well similarly to C#

Describe alternatives you've considered I've tried to pass it to dotnet interactive tool as argument, but it seems to be unsupported as well. So, it seems that assert is unusable witn dotnet interactive notebook
