Get Code Action Identifiers From Roslyn

[TanayParikh]

Currently we determine the type of code action via heuristics (ex. ends with Path for fully qualifying System.IO.Path). Optimally, we could get some kind of id/enum from roslyn which identifies the kind of the code action. This issue tracks adding support for this.

This would likely require expanding VSCodeAction to support a Kind. Alternatively we could add the Kind as part of VSCodeAction.Data.

This issue may require changes from LSP Platform / O#.

Pushing this to Preview3. PR is in progress, but haven't had time to complete it this cycle due to pull-diagnostics.

Blocked pending design review (Roslyn is considering making the ProviderName a part of the public API).

[TanayParikh]

Design review notes;

• Taking the Provider Names approach using PredefinedCode{Fix,Refactor}ProviderNames to allow Razor to filter out which Code Actions are made available to the user.
  • Doc comments in PredefinedCode{Fix,Refactor}ProviderNames.cs detailing the human process for refactors / new code action additions
  • Will consume Provider Name from string[] CodeAction.CustomTags

External, better idea of prioritization by EOW.

Should be landing shortly, unblocking the Razor use case.

The external work has been started.

Step 1; add the custom tags property for Code Actions: dotnet/roslyn#51456
