Set server GC for F# FSC/FSI

[vzarytovskii]

As we figured out here, SDK is not getting runtimeconfig.json files from F# itself, but from the https://github.com/dotnet/sdk/blob/main/src/Layout/tool_fsharp/tool_fsc.csproj:

sdk/src/Layout/redist/targets/GenerateLayout.targets

Lines 254 to 262 in a503394

	<!-- Deploy deps and runtime config for fsc.exe and fsi.exe. Both apps have exactly the same dependencies so this is Ok -->
	<Copy SourceFiles="$(FSharpDirectory)/tool_fsc.runtimeconfig.json;
	$(FSharpDirectory)/tool_fsc.deps.json;"
	DestinationFiles="$(FSharpDirectory)/fsc.runtimeconfig.json;
	$(FSharpDirectory)/fsc.deps.json;"/>
	<Copy SourceFiles="$(FSharpDirectory)/tool_fsc.runtimeconfig.json;
	$(FSharpDirectory)/tool_fsc.deps.json;"
	DestinationFiles="$(FSharpDirectory)/fsi.runtimeconfig.json;
	$(FSharpDirectory)/fsi.deps.json;"/>

Hopefully, it's the proper place to make the change, if not, please advise what would be thecorrect one.

Update: will also need to verify that these changes do affect runtimeconfig, when build is complete.

Apologies for ping, everyone, github seems to do that automatically if you re-target the branch. I will reopen it for the appropriate branch.
