[TIMOB-14285] Fix kroll-v8::nativeSetProperty() to set accessor

[garymathews]

• nativeSetProperty() does not set an accessor for custom properties, making them unavailable in JavaScript

TEST CASE

var win = Ti.UI.createWindow();
win.open();
win.applyProperties({customString: 'TEST'});
Ti.API.info('customString: ' + win.customString);
// customString should output 'TEST'

JIRA Ticket

Can we add a unit test for this? Do other platforms support this? I think Windows does...

[garymathews]

I'll add test, but this does not only affect applyProperties. Any internal calls to setProperty would fail if it is to set properties that are not defined by a Titanium proxy.
