Get app_server working on x86_64.

With this commit, app_server now compiles and runs at boot! Nothing
particularly interesting happens, just the blue background and a mouse
pointer. Remote backends are broken and not compiled in, see #8834.
Note that it won't be possible to build this quite yet, need to get
the FreeType package uploaded.

* introduced IntPoint and IntRect, which are just like BPoint and BRect,
but use integer coordinates. These are now used in ViewLayer for the
coordinate system (layout, scrolling offset, view bitmap layout)
* modest performance improvements by inlining some very often used
methods, and by preventing to go down the entire layer tree too often,
for example InvalidateScreenClipping was always called in the deep
mode, therefor it is save to assume that the tree does not have to
be traversed as soon as the clipping is already invalid
