[FEATURE]: Frames support

[mlipok]

What feature would you like, or what problem are you facing?

We need to support frames

What's your proposed solution?

@ioa747 please add support for frames events and add event handlers function to UDF

Then I can investigate

1. how we can use this in LoadWait function
2. how to enumerate frames
3. how to switch to frame
4. how to get frame content
5. how to click in element located in specific frame

Screenshots

according to:
https://learn.microsoft.com/en-us/microsoft-edge/webview2/reference/winrt/microsoft_web_webview2_core/corewebview2frame?view=webview2-winrt-1.0.3595.46

we need to get a CoreWebView2Frame by handling the CoreWebView2.FrameCreated event. when created put then to the list with relation to hGUI maybe with maps or arrays ?
IMHO arrays will be better.
