Rename Microsoft.Net.Interactive.netcore to Microsoft.Net.CSharp.Interactive.netcore

Organize Compiler Code

Move the files in the compiler that are shared by source with other projects into the Shared folder.  This combined files which weren't in a shared location and those previously in Helpers.

They prevent the files listed in the `Outputs` attribute of the
`FakeSign` target from being found.

Roll back the earlier workaround of passing `-f`.

merge stabilization into master

Fixes #873

Sometimes there are buffers with our C#/VB content types that are not added to the Running Document Table and therefore never end up in the MiscellaneousFilesWorkspace (or any workspace), such as the Source Control "Annotate" view. This change updates the Syntactic Classifier to handle such cases by parsing its initial snapshot for tagging (changes are not observed, but the known use cases of this fix are uneditable anyway).  There are some exceptions to this behavior (e.g. the Immediate window) which require us to go digging through attached views, but we default to classifying these buffers now.
