Bevy version and features

• main since Multi-draw sorted render phases if the platform supports it. #23005

[Optional] Relevant system information

Reproduced locally on macOS, and in ci on Vulkan and DX12

What you did

What went wrong

Nothing is displayed, no error log

Investigated this and I believe the problem is that for some reason the MeshUniform isn't being uploaded for meshes in sorted render phases when the view has NoIndirectDrawing.
