We would like to record additional information in the find-package stack, but we don't have the information at the point a stack entry is created. The most sane way to handle this appears to be making the stack mutable, at least under specific circumstances. To facilitate this, we need a mutable stack type. Refactor cmConstStack into cmStack, with the ability to either allow or forbid mutation of its data. Re-add cmConstStack as a type alias. This doesn't yet allow mutating cmFindPackageStack, but it's a necessary step toward being able to do so.
