The project snapshot now maintains a RazorProjectEngine as well as set
of Tag Helpers that are known for that snapshot.
Pivoted some more services to be snapshot-centric.
Also added the ability to track .cshtml documents to the project system.
For now most components just ignore document changes.
- Tied into VS4Macs ProjectExtensions in order to bootstrap our Razor world.
- We currently watch all DotNet projects with the expectation that they're the only ones that can potentially turn into Razor compatible projects.
- Added a fallback Razor project host which is used for pre-Razor SDK Razor versions (< 2.1).
- Added a default Razor project host which consumes all MSBuild data from the users packages and sets up the Razor world accordingly.
- Had to modify some existing contracts to work better with new expectations. one of these was the VS4Mac specific Workspace accessor; essentially we needed to be able to lookup a workspace from a solution.
- Some of our previous expectations about addins were wrong (not being able to directly reference your libraries). To avoid using reflection to bootstrap our types I tried out directly referencing our libraries and all worked fine.
- Refactored the DefaultRazorProjectHost in windows (since we had to in Mac) for testing purposes.

Step 1: Add HostProject
This is a somewhat complex addition to the ProjectSnapshotManager. Now
that we accept updates from the underlying IDE project system we need to
coordinate those with the Workspace.
This means that ProjectSnapshot itself now also has a version concept.
Step 2: Introduce a new project system based on CPS
We use project capabilities defined by the Razor SDK to determine
whether to rely on MSBuild evaluation to detect the configuration or
whether to fallback to assembly-based detection.
Step 3: Flow RazorConfiguration everywhere
We use now expose the RazorConfiguration to the language service and
editor. This means that we no longer need to detect the project's
configuration asynchronously, it happens much faster now.
