[macOS] With OpenGL, properties unset when contained in same instancing buffer
Reproduction steps:
1. Open the attached user's project "1019086-Poker.zip"
2. Enter Play Mode and observe the poker chip count
3. Run a Mac build with the Graphics API value set to OpenGL Core on a Mac with an integrated graphics card.
4. Observe the poker chip count
Expected results: all poker chips show as in the Editor
Actual results: bottom layer of chips (using single buffer for both UV and alpha properties) is invisible due to Alpha remaining at the default value (see attached Results.png)

Resolution Note (2021.2.X):
The bug is specific to OpenGL (WebGL/OpenGL Core) on Intel graphics cards in 2012-2015 Macs. This is because of how arrays of structs are packed in shader uniform buffers. A workaround is to make the struct fields 16 byte aligned
