[perf] optimize EDT SdkRunConfig.getState

[pq]

Speeds up SdkRunConfig.getState which necessarily runs on the Event Dispatch Thread.

The fix has two parts:

1. Move the expensive call to ModuleUtilCore.findModuleForFile(..) into an async read action (because we can) and
2. Speed up inProject because we can't background it and there's a speedy alternative to the old more expensive approach

Addresses stack traces like this:

java.lang.Throwable: Slow operations are prohibited on EDT. See SlowOperations.assertSlowOperationsAreAllowed javadoc.
