Make stack operations use AutoCloseable for safer usage with try-with-resources

[jasmith-hs]

Replaced the error-prone CallStack and Stack pop/push pattern with AutoCloseable so that pushing can be done using try-with-resources.

Added method dangerouslyGetWithoutClosing() to allow backward-compatibility with existing public methods.

Migrated all of the prod code, and the test code using CallStack pushing. Many tests using JinjavaInterpreter.pushCurrent() still need/can be migrated.

Using algebra Result for correct/explicit error handling.

New methods like AutoCloseableSupplier<Result<String, TagCycleException>> closeablePush(...), and deprecated the old methods that don't return an AutoCloseableSupplier<T>.

The way that I designed AutoCloseableSupplier and AutoCloseableImpl makes it so that you can use .map to transform what the autocloseable is, and a custom consumer is supplied that tells how to "close" the thing. And in cases where no closing needs to occur (such as error cases where nothing is pushed to a stack), there's AutoCloseableSupplier.of(value)
