  Enumeration Type Lowering: FIR code generation (PR 9)

Maps enumeration types to i32 at the FIR level. Intercepts enumeration
DerivedTypeSpec in ConvertType to produce IntegerType, lowers
enumeration constructors/constants, and generates NEXT/PREVIOUS/HUGE
intrinsic lowering with STAT boundary handling and error termination.

Files from original PR 9 plus PR 7/8 lowering additions (PREVIOUS,
STAT, void-cast fixes).
