GPU: Fix assert when using light gizmo.

Browse Source 
Blender was reporting that the GPU_TEXTURE_USAGE_HOST_READ wasn't set.
This is used to indicate that the textures needs to be read back to
CPU. Textures that don't need to be read back can be optimized by the
GPU backend.

Found during investigation of #104282.
