Fix the ComputeBoids sample on the OpenGL backend.

Having the [[block]] decorator on the nested Particle struct causes
SPIRV-Cross to not emit it (see bug). Removing the decorator from
the Particle while leaving it on the top-level struct works fine.

This fixes the issue, but validation should be added to Tint
to catch the problem (this work is tracked in https://bugs.chromium.org/p/tint/issues/detail?id=320).
