[FIR] Create CFG for files to track top-level property initialization
In order to properly analyze top-level property initialization, a control-flow graph must be created for FirFiles. This change adds the foundation for the file CFG and updates body resolve to create the CFG. Checking the CFG for proper initialization is separated into a following change to ease code review.
