VS: Installing custom built vsix does not update the tools

[majocha]

Build and install VisualFSharpDebug.vsix

VS still uses compiler exe from C:\Program Files\Microsoft Visual Studio\18\Insiders\Common7\IDE\CommonExtensions\Microsoft\FSharp\Tools

which is now older than the FCS it has.

Installation should not override the path, since you want to keep the ability to rollback a local .vsix. But the .props/.targets could be done in a way to detect custom .vsix and redirect to a locally built artifacts folder perhaps.
