Make `arrow-csv` and `arrow-json` optional for applicable crates

[crepererum]

Is your feature request related to a problem or challenge?

Currently importing crates like datafusion-expr or datafusion-common pulls in arrow with its default features, which includes the rather heavy arrow parts arrow-csv and arrow-json. Since these parts are really only required during physical execution of the respective operators & data sources, that seems rather unnessary.

Describe the solution you'd like

I see two options:

• set default-features = false for the workspace-level arrow dependency and then request the right features in the Cargo.toml files of the respective datafusion crates
• better: do NOT depend on the arrow umbrella/meta crate at all but directly on the subcrates that we need

Describe alternatives you've considered

Keeping the dependencies simple but instead suffer from longer compile times and larger build artifacts.
