[Qt][Win] Input events aren't mapped properly with windowless plugins.

https://bugs.webkit.org/show_bug.cgi?id=116094
Reviewed by Tor Arne Vestbø.

Source/WebCore:

The events are first sent properly but Flash then immediately repaints
and this causes flickering painting.
The issue is that Flash seems to be doing some input event tracking of
its own internally, using the HWND returned through NPN_GetValue(NPNVnetscapeWindow).

We are currently using two coordinate systems for windowless plugins on Windows with Qt:
- FrameView coordinates: Used for input events and ajusted with the WM_WINDOWPOSCHANGED message
- Drawable coordinates: Used by WM_PAINT and adjusted with NPP_SetWindow

This patch fixes the bug by mapping input events to the native window returned
as NPNVnetscapeWindow instead of the FrameView to ensure that those coordinates will match
the ones used by Flash internally.
With this we shouldn't be using FrameView coordinates anywhere for windowless plugins
on Windows with Qt.

Make PNGImageDecoder::rowAvailable auto-vectorizable

https://bugs.webkit.org/show_bug.cgi?id=116151

Reviewed by Benjamin Poulain.

Changed the main loops under PNGImageDecoder::rowAvailable so that they
avoid branches and non-sequential table look ups.

Together with automatic vectorization by the compiler this provides around
4x speed-up with AVX or 2x speed-up on generic x64. Shaving off 12-40% on

[Qt][Mac] Allow drawing plugins with QWindow by always using an intermediate bitmap.

https://bugs.webkit.org/show_bug.cgi?id=116620
Reviewed by Tor Arne Vestbø.

The isolation of QWidget along with QPA in Qt5 is abstracting away the native CGContext
of a QWidget and we would need to create a non-public API to be able to achieve it.
Instead of adding complexity to this rarely touched code, always draw into an
intermediate bitmap that we then paint into our QPainter afterward.

- Use CGBitmapContextCreate to allocate a buffer directly instead of creating a QPixmap
  and extract an CGContextRef out of it.
- Get rid of the "if (platformPluginWidget())" code path since we don't paint directly
  into the QWidget's backing store anymore.
- Always use m_contextRef to draw the plugin instead of alternating between direct and
  indirect drawing.

The previous fix only moved the crash location from WebKit down to QNetworkReplyHttpImpl
