Bahex 301d1370c4 Add input support to generate (#14804) ...

- closes #8523 

# Description

This PR adds pipeline input support to `generate`.
- Without input, `generate` keeps its current behavior.
- With input, each invocation of the closure is provided an item from
the input stream as pipeline input (`$in`). If/when the input stream
runs out, `generate` also stops.

Before this PR, there is no filter command that is both stateful _and_
streaming.

This PR also refactors `std/iter scan` to use `generate`, making it
streaming and more performant over larger inputs.

# User-Facing Changes
- `generate` now supports pipeline input, passing each element to the
closure as `$in` until it runs out
- `std/iter scan` is now streaming

# Tests + Formatting
Added tests to validate the new feature.

- 🟢 toolkit fmt
- 🟢 toolkit clippy
- 🟢 toolkit test
- 🟢 toolkit test stdlib
