[#793] Extended typechecking

Description

Let typechecking work on untyped instructions based not only on ExpandedOp.

My use case - debugger, where I need to attach meta coming from Expression to Typed.Instr via Meta constructor.

TODOs:

• Add a test after !1118 (merged) is merged
• Wait for #785 Workarounded this
• Great renaming after the first round of review
  • typeCheckOpImpl → typeCheckExpandedOp
  • All typechecking functions polymorphic over op - replace impl and implFinal suffix with tick, like we do in types (e.g. Contract' and Value').
