Issue description

When you select the SubViewport path to Viewport texture console starts spamming infinitely the error:

ERROR: Condition "!uniform_set" is true.
   at: draw_list_bind_uniform_set (drivers/vulkan/rendering_device_vulkan.cpp:6697)
ERROR: Uniforms were never supplied for set (3) at the time of drawing, which are required by the pipeline

After Closing godot the message continues:

Steps to reproduce

*Create Basic 3d Scene

• Create two cameras A and B
• Create a subviewport node
• attach camera B inside
• Create a meshinstance to apply a material
• attach a basic material to the mesh
• under albedo attach a new ViewportTexture
• Select the SubViewport
• Error should happen

#52528 seems to fix some, but not all, of the errors.

I tested and the error spam was fixed by #54489.

I'm not sure the ViewportTexture actually works though, there's still

ERROR: Viewport Texture must be set to use it.
   at: get_height (scene/main/viewport.cpp:113)
ERROR: Viewport Texture must be set to use it.
   at: get_width (scene/main/viewport.cpp:108)

and the preview is garbled, but that's probably something to track in a separate issue.
