All internal-flag tests now extract the packed value and verify
bit 24 is set/clear for the correct entities, instead of just
checking configure_entity_() call presence.
Move set_internal(), set_disabled_by_default(), set_entity_category(),
and set_device() to protected on EntityBase. These were codegen-only
setters never intended for runtime use.
internal, disabled_by_default, and entity_category are now packed into
the existing configure_entity_() uint32 parameter alongside string
indices, eliminating up to 3 separate function calls per entity.
set_device() is renamed to set_device_() per protected naming convention
and remains a separate call (pointer can't be packed).
Entity category integer mapping is derived from cv.ENTITY_CATEGORIES
to stay in sync with the C++ enum automatically.
