Remove dependency on Editor and EditorFeatures from Microsoft.CodeAnalysis.LanguageServer.Protocol project

[tmat]

• Move FindUsagesContext to Features
• Avoid dependency on editor types such as ClassifiedTextElement, ImageElement, etc. (https://devdiv.visualstudio.com/DevDiv/_workitems/edit/1361656)
• Move tag ids to Features (DefinitionHighlightTag.TagId, WrittenReferenceHighlightTag.TagId, ReferenceHighlightTag.TagId)
• Remove IThreadingContext: https://github.com/dotnet/roslyn/projects/45#card-20619668
• Move IntellisenseQuickInfoBuilderContext to Features
• Move IInlineRenameService to features / switch implementation for rename - https://sourceroslyn.io/#Microsoft.CodeAnalysis.LanguageServer.Protocol/Handler/Rename/RenameHandler.cs,45
• Remove dependency on global options (requires LSP settings to be implemented by the platform).

The LSP layer does not depend on editor features, and almost everything has been moved down. See
