Inject sys.frozen and sys.frozendllhandle as constructor arguments instead of referencing them directly in RegistryEntries.

[junkmd]

sys.frozen and sys.frozendllhandle are constants in sys that exist only when running under embedding tools. These constants are not present in a standard Python environment.

Using hasattr or getattr repeatedly to retrieve these constants is redundant.
To address this, they are now accessed only once within the Registrar constructor, and their values are injected into RegistryEntries.
