Description
We should consider support for mesh picking without using physics engine.
There's an older PR which implements this, but it would need to be updated to latest changes with the engine, or at least used as a base: https://github.com/playcanvas/engine/pull/989

Research direction
Start by reviewing the older implementation in pull request #989, then compare it with the current engine changes. Update the approach so mesh picking works for mesh instances without the physics engine, and verify that intersection results are returned correctly.
