Fix mapping to/from global coordinates for child/embedded windows.

QWidget's mapToGlobal() and mapFromGlobal() functions assumed that
if the widget reports it's a window or if it has no parent widget, it
must be a top level window whose coordinates are in global coordinates.
This is not true for child QWindows or embedded native windows
(QAxWidgets).

Changed the logic for mapping coordinates to use equivalent methods
from QWindow if widget has a window handle, and changed QWindow's
methods to map coordinates using native methods if window is embedded.

Also fixed newly failing accessibility autotest. The geometry related
failures there popped up because now the position of the rect returned

Move QRecursiveMutexPrivate to qmutex.cpp and mark inline

Disassembly of the optimised code shows that the compiler was already
inlining the bodies of one or both functions (since they're in the same
.cpp, it's allowed to do that).

However, since there was no "inline" marker, the compiler was also
emitting an out-of-line copy, which wasn't used by anyone, as the class
is not exported.

So add the marker. To make sure that they don't get used by accident
elsewhere, the class is moved to the .cpp file too.
