Track configuration initialization state for using loggers

[zakkak]

Tracks configuration initialization state in a boolean to determine if loggers are ready to be used. Useful when we need to log an error due to an early failure.

Closes #42084

This seems to result in the process freezing after printing the exception... Converting to draft for now.

False alarm, it only freezes if we pass -XX:MissingRegistrationReportingMode=Exit, which is unrelated to this PR.

However, while looking at this I noticed that there is also com.oracle.svm.core.jdk.resources.MissingResourceRegistrationError that we need to catch, but it's not public API.

@radcortez how do you find this idea?

It's been a while since I looked at how the early boot works with native image generation, but are we using the delayed handler in this case?

I don't really know, but a quick search led me to

quarkus/core/deployment/src/main/java/io/quarkus/deployment/steps/MainClassBuildStep.java

Lines 322 to 339 in bbb1009

	// an exception was thrown before logging was actually setup, we simply dump everything to the console
	// we don't do this for dev mode, as on startup failure dev mode sets up its own logging
	if (launchMode.getLaunchMode() != LaunchMode.DEVELOPMENT) {
	ResultHandle delayedHandler = cb
	.readStaticField(
	FieldDescriptor.of(InitialConfigurator.class, "DELAYED_HANDLER", QuarkusDelayedHandler.class));
	ResultHandle isActivated = cb.invokeVirtualMethod(
	ofMethod(QuarkusDelayedHandler.class, "isActivated", boolean.class),
	delayedHandler);
	BytecodeCreator isActivatedFalse = cb.ifNonZero(isActivated).falseBranch();
	ResultHandle handlersArray = isActivatedFalse.newArray(Handler.class, 1);
	isActivatedFalse.writeArrayValue(handlersArray, 0,
	isActivatedFalse.newInstance(ofConstructor(ConsoleHandler.class)));
	isActivatedFalse.invokeVirtualMethod(
	ofMethod(QuarkusDelayedHandler.class, "setHandlers", Handler[].class, Handler[].class),
	delayedHandler, handlersArray);
	isActivatedFalse.breakScope();
	}

which indicates that you are right.

Maybe what we want is a way to dump out the delayed handler queue in the event of error. I know we're able to do that at run time at least, so it should be possible to do so at build time as well?
