MINOR: enable dyn_cmp_dict feature on arrow for physical expr crate

[isidentical]

Seems like when we are executing the test suite for the physical exprs in a standalone way (which I tend to do quite a lot 😄), it fails with a test requiring a specific feature from arrow-rs (dyn_cmp_dict). It is already turned on for datafusion-core, so ideally this should not change anything.

 $ cargo test --package datafusion-physical-expr                                                                                                     1,135s

Can we only enable this for dev, dyn_cmp_dict is an extremely heavy feature that is intentionally not enabled by default?

Makes sense @tustvold, I've changed the PR to only enable it as part of the dev dependencies.
