Initial cohost server implementation (#9674)
Browse files Browse the repository at this point in the history 
First part of #9519
Razor side of dotnet/roslyn#70819

This PR consumes the new Cohost server from Roslyn, and when enabled,
moves DocumentColor requests from being handled by our existing Razor
Language Server, to instead be handled by the new server. There is
currently no sharing of project system data or anything like that yet. A
few TODOs for follow ups, ~can't be merged, and indeed won't build,
until a Roslyn package is available etc. but~ it's reviewable while we
keep working, and more important its shippable in its "off" state.

~Ignore the last commit, obviously won't be merged :)~
