Allows users to opt into using their workspace typescript.tsdk setting to specify the path to their typescript install.
Also, fixes a bug when the global tsdk setting points to the workspace version of typescript, our ts selector interface can get confused on which version is currently active. The fix adds a check using the local storage value to show the correct active version.

* Rename TypeDefinitionProvider to TypeImeplementationProvider
**bug**
In #18346, I originally called the new go to implementation provider api `ImplementationProvider` which we then decided to rename to `TypeDefinitionProvider`. At the time, I didn't realize that a type definition was actually its own, unrelated concept.
**Fix**
Rename `TypeDefinitionProvider` to `TypeImplementationProvider` to make it clear what the purpose and use of this api is.
