GPU: Treat negative light exp same as 0.
...
Based on #12507 and some tests, seems like negative exponents are also
fixed to a 1.0f result.

Vulkan: Always write gl_PointSize, fixes #12364 . Remove unnecessary predeclaration of gl_Position.
...
Replaces #12393 .
The predeclaration used to be required by early versions of glslang but is no longer. Since the GLSL compiler is controlled by us, we don't need to fear incompatibilities.

Workaround ARM Mali depth hardware bug. Fixes #11937
...
When triangles coincide with the Z=1 plane in specific ways, triggered
by Burnout Legends' sky for example, the depth buffer gets corrupted.
This is worked around here by slightly rescaling Z. This type of
workaround is recommended by ARM driver engineers.
Ugly but what can you do when the hardware is bugged. I've done quick
tests on a number of games with no issues.
