Allow to asynchronously notify extensions of no-restart changes

[ia3andy]

This allows a clean way to notify extensions of no-restart changes like there: quarkiverse/quarkus-web-bundler#217:

RuntimeUpdatesProcessor.INSTANCE
                .notifyExtensions(noRestartChanges)

This also allows to reset the compileProblem asynchronously.

For context, when the change is already handled/compiled by the underlying process, triggering a doScan() is not necessary and could even be an issue. Still, extensions needs to be notified of the change.

Tested with web-bundler

Why the new locks?

For the context, I want to make sure this won't cause problems as you asked for a backport.
