Optimize particles vertex data

Use uchar instead of float for vertex data that doesn't need float.
Continue using floats in shaders. Also remove animY2, which is same as
animY1. These changes reduce memory usage especially when the amount
of particles increases.

Testing on windows, memory reductions with emitters/trailemitter
example were:
- OpenGL: 82.7 MB -> 76.5 MB
- Vulkan: 130.8 MB -> 126.3 MB
- D3D11: 143.7 MB -> 135.8 MB
