Many of our VB projects today rely on having an empty default namespace
and explicitly specifying the full namespace in source. In the new SDK /
dir props world this can only be done by explicitly marking the
namespace as empty in the project file. Can't do the centralized control
that we do today.

In the new SDK we no longer have a need for ProjectGuid. This change
will:

- Remove ProjectGuid from project files
- Remove Name + Project items from ProjectReference entries
- Change BuildBoss to enforce both of these items

The warning B40057 used to be suppressed at a global level in PCL /
Desktop projects. The SDK does not suppress this warning and hence
converting to the new SDK caused this to show up.

Previously a number of developers fixed this problem individually. The
correct solution is to suppress it globally as was done previously.

Introduce a more flexible service to allow languages to plug into common comment/uncomment behavior.

This diagnostic analyzer checks the index values of all placeholders in a format
string. If a placeholder in the string is out of range, a warning message is displayed.

fixes bug #15856

* Added glyph to completion item
* Added type info test for InternalsVisibleToAttribute (SemanticModel) including test
* Added support for three out of four ways to strong name an assembly:
  *  By csproj property *AssemblyOriginatorKeyFile* (was already supported)
  *  By compiler option (was already supported)
  *  By *AssemblyKeyFileAttribute* and *AssemblyKeyNameAttribute* (new, requires compilation of every assembly). Test case added.
  *  Not supported: By Assembly Linker (IMO not possible)
* Added test for delayed signing

Fixes #19141

This is an automated migration of our project files to the new SDK /
PackageReference.  It is done using the tool located here:
