See #30264

Added DotNet global tool for code formatting.

Tool can be run on a project, solution, or folder containing a
project or solution. Tool pulls formatting configuration from an
.editorconfig if present, otherwise formats with roslyn defaults.

This produces a new free-threaded, well factored API for adding projects
to the VisualStudioWorkspace. The core type is the VisualStudioProject
which is a free-threaded API that you can use to push information over.
CSharpProjectShim, VisualBasicProject and CPSProject each have an
instance of VisualStudioProject that they push things through.

The inheritence model here is now smaller. CSharpProjectShim and
VisualBasicProject inherit from AbstractLegacyProject, but that's it.
CPSProject now inherits nothing, and AbstractProject is here purely
for TypeScript back-compat until they're moved onto the new APIs. The
expectation is F# and TypeScript both move to VisualStudioProject, which
we make public in some form. Then that type will go away.

This is a package we depend on via normal means, and expect it to
be referenced in our NuGet packages as they are today.

Our dependency Microsoft.VisualStudio.Language.Intellisense already
carries forward the version we should be referencing; this seems to
be an oversight of a generic upgrade to higher packages that now
means we're trying to reference something higher than it.

Some of these were previously used by things that have moved to
https://github.com/dotnet/roslyn-tools and
https://github.com/dotnet/roslyn-sdk.

There are real versions of these packages now, so we can stop using
-alpha versions. Some other packages were upgraded to avoid package
downgrade concerns.

I am removing our explicit references to Microsoft.VisualStudio.Imaging
and Microsoft.VisualStudio.Utilities; both of these are carried along
in references to Shell.15.0, and trying to state them explicitly just
results in package downgrade warnings.
