Kernel: Separate GenericFramebufferConsole implementation

Browse source 
The GenericFramebufferConsoleImpl class implements the logic without
taking into account any other details such as synchronization. The
GenericFramebufferConsole class then is a simple wrapper around
GenericFramebufferConsoleImpl that takes care of synchronization.

This allows us to re-use this implementation with e.g. different
synchronization schemes.
