Remove unnecessary alternate create_texture path in prepare_asset for…

… Image (bevyengine#6671)

# Objective

`prepare_asset` for Image has an alternate path for texture creation that is used when the image is not compressed and does not contain mipmaps. This additional code path is unnecessary as `render_device.create_texture_with_data()` will handle both cases correctly.

## Solution

Use `render_device.create_texture_with_data()` in all cases.

Tested successfully with the following examples:
- load_gltf
- render_to_texture
- texture
- 3d_shapes
- sprite
- sprite_sheet
- array_texture
- shader_material_screenspace_texture
- skybox (though this already would use the `create_texture_with_data()` branch anyway)
