[TIMOB-24637] Windows: Accessing generic collections throws exception

TIMOB-24637

Accessing generic collection property/method such as System.Collections.Generic.IList<T>.Add throws exception.

var win = Ti.UI.createWindow({
    backgroundColor: 'green'
});
var button = Ti.UI.createButton({
    title: 'Show Alert'
});
button.addEventListener('click', function () {
    var MessageDialog = require('Windows.UI.Popups.MessageDialog'),
        UICommand = require('Windows.UI.Popups.UICommand'),
        PropertyValue = require('Windows.Foundation.PropertyValue'),
        Int32 = require('System.Int32');

    var dialog = new MessageDialog('My Message');
    dialog.Title = 'My Title';
    dialog.DefaultCommandIndex = 0;
    dialog.Commands.Add(new UICommand('OK', null, PropertyValue.CreateInt32(0)));
    dialog.Commands.Add(new UICommand('Cancel', null, PropertyValue.CreateInt32(1)));
    dialog.ShowAsync().then(function (command) {
        var id = Int32.cast(command.Id);
        alert((id == 0) ? 'Pushed "OK"' : 'Pushed "Cancel"')
    });
});

win.add(button);
win.open();

Expected:

• This should show alert dialog with two buttons: [OK] [Cancel] when you click "Show Alert"
• When you click [OK] you should see "Pushed "OK"
• When you click [Cancel] you should see "Pushed "Cancel"

This also implements TIMOB-24646

var List = require('System.Collections.Generic.List<System.Int32>'),
    Int32 = require('System.Int32');
var vec = new List();

vec.Add(Int32.cast(0));
vec.Add(Int32.cast(1));
vec.Add(Int32.cast(2));

Ti.API.info(vec[1]); // this should print "1"
vec[1] = 100;
Ti.API.info(vec[1]); // this should print "100"

@infosia If we want this in 2.1.1, we need a backport to 2_1_X.
