Windows: Implement native Internet Explorer in qtwebview

Pending changes

QAxWindow + WebView

• Proof of concept: Split apart Active Qt to create a QAxWindow: https://codereview.qt-project.org/#/c/94229/
• Add impl: https://codereview.qt-project.org/#/c/96684/
• Dumpcpp support QAxWindow https://codereview.qt-project.org/105024

Proof of concept

Attempt to use a QAxWidget-based browser in assistant and potentially Creator. This is a prototype, idea being to develop interfaces for the classes of QtWebView that actually are useful.

• Use IWebBrowser via Active Qt/QAxWidget in assistant : https://codereview.qt-project.org/#/c/100930/

IDocHostUIHandler::TranslateUrl() might be interesting for URL rewriting.

Abandoned changes

• Attempt without Active Qt: https://codereview.qt-project.org/#/c/93687/ (probably doomed, catching events and fine-tuning window-handling requires most of Active Qt).
