Clamp zorder calculation to [0.0, 1.0]
On the Apple M1 chipset with clang 14 and above, the optimizer
will replace fmul/fsub with fmsub, which frequently produces near-zero
negative values. The viewport z clipping space is [0.0, 1.0], which can
result in the top-most layer being clipped.
Pick-to: 6.5 6.4 6.2
Fixes: QTBUG-109739
