[#105] Add versions of `finalizeParamCallingDoc`

Description

Problem: currently this function is tied to specific case when user has contract parameter at the top of the stack after initial unpair instruction. This makes this function unusable e.g. when the entire contract is written via Indigo.

Solution: add Indigo version of finalizeParamCallingDoc.

This required generalizing that function to accept proxy with parameter rather that requiring it to be at the top of the stack; old behaviour is retained in finalizeParamCallingDocP.

Another solution is to have finalizeParamCallingDocC which accepts the whole ContractCode which we eventually have even with Indigo; this function is provided as well.
