Move the tooltip out of the way of very large mouse cursors
Users that have large mouse pointers configured in their settings
can not see tooltips, as they are obscured by the pointer.
Native applications on Windows and macOS have the same problem,
which includes the tooltips for the minimize/maximize/close controls
in the window frame of e.g. Explorer.
Introduce QPlatformCursor::size that returns a value that is based
on the user's settings, or a default value. We can then use that
value to move the tooltip out of the way.
On Windows, the calculation of the cursor size is based on
experimenting with the settings, which are in logical independent
pixels. The placement of the tooltip attempts to keep existing
behavior, and to not end up with a tooltip that's very far away
from the tip of the arrow even for very large mouse cursors.
[ChangeLog][QtWidgets][QToolTip] Make sure that the tooltip
is not obscured by very large mouse pointers on Windows and macOS.
