    Added a muranoPL-specific override of 'call'

    Yaql's standard system function 'call' was not working properly in
    MuranoPL because murano relies on object-specific context containing
    definitions of the methods of appropriate class.

    This patch adds a MuranoPL-specific override of this function which
    creates an appropriate method-invocation AST and executes it. This
    will invoke regular muranoPl's override of operator_. thus causing all
    the appropriate type and object contexts to be created for the call.

    Closes-bug: #1595174
