Text: Fix kerning when horizontalAlignment is set to center

When horizontalAlignment is set to center, alignedX will potentially
return a position that is not pixel-aligned. This causes issues with
text layout lower in the stack, leading to incorrect kerning.
Rounding the position makes sure we always have a pixel-aligned
position.

Note that this adapts the same alignment approach as centering done
by anchors, so the two will now be more consistent.

[ChangeLog][QtQuick][Text] Fixed kerning when horizontalAlignment is
set to center.
