Remove two unused helper functions that were left behind after refactoring:
1. unpackUVec3: Left over from commit 4329aaa31c ("GPU: Apply color
test mask as a uint") which refactored color test to use
roundAndScaleTo8x4 with direct uint comparison instead of unpacking
to uvec3 components.
2. packFloatsTo8x4: Left over from commit aec22491fe ("Don't expand
alphaColorRef to 128 bytes") which changed u_alphacolorref from vec4
to uint, making the float-to-uint packing function unnecessary.
Both functions were defined but never called, wasting shader compilation
time and binary size for shaders that enable color testing.
