fix(gnovm): charge gas for type checking the Go AST statically

[odeke-em]

Typechecking the Go abstract syntax tree incurs a huge penalty as part of the GnoVM's functionality when starting up and before running a package, hence it is only natural to also charge a cost. At first the charges shall be naive and as we expend more thought and research, shall refine what and how much to charge.
