Refactors the ts DiagnosticManager to be shared between language providers.  To do this:

- Make sure we always maintain a complete list of diagnostics in the extension. But only update the vscode.DiagnosticCollection with the ones we care about

- Add the concept of a diagnostic language. This is needed now that we only have a single collection. Use the diagnostic language to determine which diagnostics to filter out using `typescript.validate` and `javascript.validate`

- Add a diagnosticSetting class to track settings for different languages (js and ts)

Fixes #54359
