Update to use progress reporting as defined in LSP 3.15. The VSCode extension has also been updated and should now be making use of this.
Properly declare that we should support code actions. This helps with some clients that rely on this information to enable code actions (thanks @jacg).
Fix a race condition caused by sharing the finder cache between concurrent compilations.
Avoid normalizing include dirs. This avoids issues where the same file ends up twice in the module graph, e.g., with different casing for drive letters.
