Subject: Add QOffScreenSurface platform API abstraction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This follows the work done in 6ff79478a44fce12ca18832a56db4a370a9ff417.

The API is available by including qoffscreensurface.h, scoped in
the QPlatformInterface namespace. The namespace
exposes platform specific type-safe interfaces that provide:

 a) Factory functions for adopting native contexts, e.g.

    QAndroidPlatformOffscreenSurface::fromNative(ANativeWindow);

 b) Access to underlying native handles, e.g.

    surface->platformInterface<QAndroidPlatformOffscreenSurface>()
                ->nativeSurface()

Fixes: QTBUG-85874
Change-Id: I29c459866e0355a52320d5d473e8b147e050acb3
