Should DevKit generally be a capitalized K if it's two words? Question applies to the PR in general. I mostly worry if a case sensitivity issue breaks us somewhere... 😄

Binary name is DevKit but the package name is Devkit?

Package name is DevKit actually, I'll fix. I think nuget ignores case on package names

Requires server side change - dotnet/roslyn#70875
These optional devkit dependencies are currently shipped inside the devkit extension, but loaded into the language server process.
That makes it hard to use internal Roslyn APIs in these dependencies because:
This PR updates the C# extension to instead ship its own devkit dependencies. They are not loaded when using C# standalone. This allows us to use internal APIs in the devkit deps without requiring a devkit version update each time they change.
We considered a runtime download of the devkit dependencies (similar to how O# is acquired), but the size of the dependencies (small, around 2 MB) and the complexity of publishing to a CDN led us to this approach.
Resolves dotnet/roslyn#69467
TODO - Draft until server side change goes in.
