I seem to have broken something... I'm going to see if I can fix this, otherwise I'll open a new branch with the changes squashed into it. |

Decided that this is unfix-able with my knowledge of git, opened #7183 |

Fixes #6763
Description
Supports getting the vertices out of the ray query with a new function. In naga's extended WGSL language this requires
acceleration_structure<vertex_return>, even though other shader languages don't require this, due to validation requirements. If we go the same route as other shader languages, the validation requirements (as far as I can tell) areget*HitVertexPositionstags ray query object. Thisray_querythen needs to find all uses of itself - iterating through all blocks it's valid in and finding anyrayQueryInitializeand tagging allacceleration_structures. This alternate design could also lead to more user confusion. The implemented design instead disallowsrayQueryInitializeinitializing aray_query<vertex_return>with a untaged acceleration structure and disallowing callingget*HitVertexPositionswith an untaggedray_query.Testing
Adds an example which demonstrates the use of the newly added function. Adds two tests for invalid uses of this flag.
