Using OIT and gizmos together panics

What you did

Used OIT and gizmos at the same time. Specifically, rendering gizmos on a camera with OrderIndependentTransparencySettings is what causes the problem.

What went wrong

wgpu error: Validation Error

Caused by:
  In RenderPass::end
    In a draw command, kind: Draw
      The BindGroupLayout with 'mesh_view_layout_oit' label of current set BindGroup with 'mesh_view_bind_group' label at index 0 is not compatible with the corresponding BindGroupLayout with 'mesh_view_layout' label of RenderPipeline with 'LineGizmo 3d Pipeline' label
        Assigned entry with binding 34 not found in expected bind group layout
        Assigned entry with binding 35 not found in expected bind group layout
        Assigned entry with binding 36 not found in expected bind group layout

I'm pretty sure this is just caused by the 3d gizmo pipeline not adjusting its mesh pipeline key when the extracted view has OrderIndependentTransparencySettings.

I'm happy to fix this myself :)
