[Feature Request] StageWebView::userAgent support

[itlancer]

Feature Description

AIR should have ability to set up user agent for StageWebView. It very useful for some cases, especially for retail kiosks and to display specific mobile/desktop versions of websites. Earlier it was possible with HTMLLoader::userAgent but now HTMLLoader deprecated and removed so we have no workarounds anymore.

Right now it available for Windows using AIR 51.2 with userAgent parameter in StageWebView configuration object. Thanks!

Hope to see it for other platforms. Especially for Android.

@ajwfrost, I think it should be properly documented here: https://airsdk.dev/reference/actionscript/3.0/flash/media/StageWebView.html#StageWebView()
