Virtualize menu not available about recaf-3x-issues

[Col-E]

Saw you commented on YT, but can't seem to reply there unless you deleted it.

Anyways, the visualize menu only appears when the feature is supported for the given method:

private boolean canUseVm() {
	// Can only be run on JVM classes
	if (!isOwnerJvmClass())
		return false;
	// SSVM must have been initialized
	SsvmIntegration ssvm = RecafUI.getController().getServices().getSsvmIntegration();
	if (!ssvm.isInitialized())
		return false;
	// Cannot run on abstract/native methods
	int access = methodInfo.getAccess();
	return !AccessFlag.isAbstract(access) && !AccessFlag.isNative(access);
}

SSVM has its own page in the config menu. You can check if its active in there, which it should be by default.

To avoid confusion, it would be probably be a good idea on disabling the action instead of removing it.
On click, we could tell then the requirements for it.

It would probably be better if it said why exactly. I got the menu to pull up on a hello world .class, but it appeared to crash Recaf for a bit:

Then the window pulled up. When I clicked optimize it lagged out again for a bit, then gave this error:

Update: I turned off the "remote vm" thing and it seemed to optimize fine.

Optimizing isn't working everywhere where I want it to be but it's working good enough.
