Added support for getting the arguments of mock function call for a specific call count

[mahigadamsetty]

Summary

The purpose of this change is to enable asserting the arguments of a mock function for a specific call count.

Changes

Updated the Mock struct to hold the map of methodName to a slice of calls instead of just a slice of Calls, this will be used to extract the calls for a given methodName easily

Motivation

For instance, when a method is invoked multiple times within the code, and there's a need to verify the arguments for a particular call count, this enhancement proves beneficial.

actualObject.ProcessData("data1")
actualObject.ProcessData("data2")

with the new API, can assert the argument for a second call like this .

returnArgs := mockedObject.ArgsForCallCount(t, "ProcessData", 1)
if assert.Equal(t, 1, len(returnArgs)) {
     assert.Equal(t, "data2", returnArgs[0])			
}

In general, I do not think this API should be added because it does not encourage best testing practices. If testing for state then a mock can be prepared with the expected calls and AssertExpectations used.

Can you demonstrate a specific test case which can't be written using the existing API?

It's also quite unclear what a call "count" is in this context.

This is a breaking change.
