don't crash without features bevy_pbr, ktx2, zstd (#14020)

# Objective

- Fixes #13728 

## Solution

- add a new feature `smaa_luts`. if enables, it also enables `ktx2` and
`zstd`. if not, it doesn't load the files but use placeholders instead
- adds all the resources needed in the same places that system that uses
them are added.
