[[CHORE]] Refactor var initialization tracking

Conceptually, the initialization state of a given variable is a property
of that variable. Model that relationship in the code organization by
tracking variable initialization using a dedicated property on the
representation of the variable itself. Beyond improving code clarity
(the "label" objects remain the single source of truth for the state of
each variable), this also reduces memory allocation costs (no new
objects need to be created).
