Implement supporting of additional parameters in extension functions

[olxmute]

Now we can create mapstruct method only with one parameter, that will become receiver in extension function. I think it would be great, if we could create methods with additional parameters. First parameter as receiver of extension function and others as input parameters.

Example:

data class EmployeeModel(val firstName: String)
data class EmployeeCompanyView(val firstName: String, val company: String)

@Mappings(
  Mapping(target = "company", source = "company")
)
abstract fun toEmployeeCompanyView(employeeModel: EmployeeModel, company: String): EmployeeCompanyView

Compiled to:

fun EmployeeModel.toEmployeeCompanyView(company: String) =
    Mappers.getMapper(EmployeeMapper::class.java).toEmployeeCompanyView(this, company)

So we can call:

val model = EmployeeModel("Alex")
val view = model.toEmployeeCompanyView("amazon")
