GetReferencesForCompilation Problem in Android

```
var corLib = MetadataReference.CreateFromAssemblyInternal(typeof(object).GetTypeInfo().Assembly);
references.Add(corLib);
```
I found codes in class CodeAnalysis.Scripting.Script.It looks to provide a default assembly metadata reference.However, It cause a error in Android because the assembly is in the .apk file.

The mistake was like
```
Could not find a part of the path "/data/app/…………/mscorlib.dll"
```
I found issues #23537 , #24442.I think it is the same problem

I've tried using other methods to read the assemblies I need, but I can't get around here.

I think there should be a way to provide the metadata reference by myelf.

Start by inspecting CodeAnalysis.Scripting.Script.It and the MetadataReference.CreateFromAssemblyInternal call shown in the report, then compare the related issues #23537 and #24442. Done means scripting can obtain the required default assembly metadata reference on Android without trying to read mscorlib.dll from an APK path.
