feat(step-generation): more compact Python generation for dicts

[ddcc4]

Overview

The custom liquid class dict for define_liquid_class() is kind of big. This PR makes the dict formatting a bit more compact: if all the entries in the dict are scalar, and their total length is short-ish, we will emit the dict on a single line.

Before:

"offset": {
    "x": 1,
    "y": 0,
    "z": 5,
},

After:

"offset": {"x": 1, "y": 0, "z": 5},

(See tests for other examples.)

This PR also cleans up the code for emitting lists of pairs as Python tuples that was introduced in PR #18558.

Test Plan and Hands on Testing

Added/updated unit tests.

Risk assessment

Low.

makes more sense to have a separate fn for this, thanks!

[jerader]

this decreases the number of lines for the custom liquid class properties by a lot. thanks!
