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-3717] When pulling in an actor FBX, two entities are spawned & [ATOM-15258] Clicking and Dragging fbx file into viewport produces 2 entities
* Added another operation to the CanSpawnEntityForProduct that checks the other products and can veto the creation process.
* The model product will not create an entity in case there is already an actor exported, which prevents the issue reported by two different teams/users.
* ensure brute force ray intersection works in the same space as kd-tree intersection
* add additional tests for ray casts against meshes using brute force approach
* update api and add some additional test cases
* comment tidy-up and other small updates/fixes for ray intersection code
* fix issue with values at the end of a ray
