Fixes ISSUE-45245: Deprecation warnings with Java 11 because of finalize method

Object.finalize() method has been deprecated since Java 9 and as such it
generates a warning when being used.
It was used in DevicePrinterJavaPOS and DeviceDisplayJavaPOS to release
several reserved resources when the Objects ceased to exist.

The alternative implemented here adds a new default close() method to the
interfaces DeviceDisplay, DevicePrinter and DeviceFiscalPrinter that
allows to close and release all those resources on a Runtime jvm
ShutDownHook. Effectively doing what the finalize method was doing previously
but more centralized.
