SwViewShell::ImplEndAction: avoid direct PaintDesktop()
With double-buffering enabled and typing quickly, one saw blinks in the
text sometimes. The reason was that PaintDesktop() painted directly
outside SwViewShell::Paint().
The problem is more visible with VCL_DOUBLEBUFFERING_AVOID_PAINT=1,
loading a simple document + pressing a key draw an unexpected white
rectangle.
Given that InvalidateWindows() already calls PaintDesktop() inside
Paint() implicitly (via SwViewShell::Paint()), fix the problem by just
avoiding the DLPrePaint2() + PaintDesktop() + DLPostPaint2() calls.

SwViewShell::DLPrePaint2: fix missing clipping for the non-buffered case
With this, if the sw window is small enough that the page shadow is
supposed to be under the sidebar, we no longer paint the shadow over the
sidebar.
In the non-double-buffered case the output is a window, so
SdrPaintWindow::PreparePreRenderDevice() does its own buffering, and
clipping is taken care of when that buffer is copied to the window in
SdrPreRenderDevice::OutputPreRenderDevice().
This wasn't a problem before, as either the output was a non-screen
device or UI elements were painted (like the sidebar), but never both at
the same time.
