Remove NeedsZWHack old Mali workaround in vertex shaders. The new transform math seems to have fixed it some other way.

Not sure if we can find a better way, I suppose
we could clamp vertex coordinates that are in this range instead, if it
turns out that this somehow breaks something.

This matches some earlier test results by Unknown where we could see
that only every second value was used, and is the only explanation I can
come up with for the Afterburner problem, having now traced all the
depth math properly.
Fixes #21785 - and hopefully doesn't break anything else.
