Code Style for trailing commas

[alrz]

• Prefer trailing commas in multi-line syntax lists (enum declarations, object/collection initializers, etc)
• Prefer no trailing commas
• None (leave as-is)

This work is in-progress in #54859 for the other request of the same feature #25206.

However, the option isn't a tristate. It's a true/false where true means "force" trailing commas, and false means "keep as-is". Tagging @CyrusNajmabadi @sharwell for thoughts of making it tristate.

@Youssef1313 Did this ever get anywhere? Came here from #25206 hoping there would be a solution. Seems you've already solved this but that you never got the feedback you wanted?
