nit: have you tried implementing more tests?
- FROM three different image.
- Copy symlink.
- Overwriting a file FROM first image with the file FROM the second image.
- Image with cycle symlink inside.

I enabled the disabled TestDoCacheProbe/MultiStage test and added a symlink copy. This tests the basics of cache probe for multi-stage. We'll do more integration testing in envbuilder.

This PR adds support for
imagefswhich currently only supports pre-caching requested files. This means that Dockerfile instructions are resolved ahead of time to figure out which files to cache.This allows tar archives to be walked once and since files are hashed as-we-go, the implementation is also memory efficient.
Once envbuilder updates to this fork, tha issue coder/envbuilder#230 will be resolved.
