[code-reflection] RFR: Simplify Interpreter invocation

[Paul Sandoz]

The overloaded `Interpreter.invoke` methods are reduced to just two methods. If the invokeable operation captures values then corresponding captured arguments must be appended, in order, to the list of arguments for invocation (those correspond to the invokeable operation's parameter, in order).
