Fix VaeImageProcessorLDM3D ignoring constructor arguments (#14429)

Fixes #14429

VaeImageProcessorLDM3D documents constructor arguments (do_resize, vae_scale_factor, resample, do_normalize), but previously called super().__init__() with no arguments.

Because VaeImageProcessor.__init__ is decorated with @register_to_config, calling super().__init__() with no arguments caused VaeImageProcessor to register its own default values (do_resize=True, vae_scale_factor=8, resample="lanczos", do_normalize=True) onto self.config, clobbering any non-default values supplied during initialization of VaeImageProcessorLDM3D.

This PR forwards do_resize, vae_scale_factor, resample, and do_normalize directly to super().__init__(...), matching the pattern used by sibling subclasses in the same module (IPAdapterMaskProcessor and PixArtImageProcessor).

Validation

• Added test_vae_image_processor_ldm3d_config in tests/others/test_image_processor.py to verify that custom constructor arguments are properly preserved in self.config and that default values continue to function as expected.
• Verified test passes locally.
• Formatted and linted with ruff format and ruff check.
