Currently, the first time a raycast is attempted for a model, the raycast will fail and the model's kdtree will asynchronously get built. This breaks the vegetation system, which expects the queries to always work. This adds in a brute-force fallback for use while the kdtree is building. However, other use cases like the Editor mouse cursor selection raycast still should get the current "silent failure" behavior, because otherwise the Editor will lock up for several seconds the first time the mouse moves over an extremely complex model.
* [LYN-3099] Fix vegetation raycasts to use bounded ray queries instead of FLT_MAX.
Raycasts with a distance of FLT_MAX sometimes overflowed deep in IntersectSegmentTriangleCCW, so it's better to have strict start/end positional queries. We have specific starts and ends anyways, so it's a safer approach anyways.
This also adds support for Non-Uniform Scale for meshes, since it was clearly not working correctly in vegetation when testing various scaled meshes.
* Addressed PR feedback
