MIR: Add minimal typechecker

Context

This builds on changes from !10006 (merged) and !9999 (merged) adds a minimal typechecker on top of the generated AST. The typechecker just returns a boolean to indicate the result. Also it only checks for a minimal subset of Michelson instructions which is required to process the Fibonacci listing from !9906 (merged).

Closes #6212 (closed).
