Make print() break long List and Object Values over multiple line

[dylanowen]

This builds upon #2797 to add multiline support for ObjectValues and ListValues.
Example:

{ trip( obj: {wheelchair: false, smallObj: {a: 1}, largeObj: {wheelchair: false, smallObj: {a: 1}, arriveBy: false, includePlannedCancellations: true, transitDistanceReluctance: 2000, anotherLongFieldName: "Lots and lots and lots and lots of text"}, arriveBy: false, includePlannedCancellations: true, transitDistanceReluctance: 2000, anotherLongFieldName: "Lots and lots and lots and lots of text"} ) { dateTime } another( list: [["small array", "small", "small"], ["Lots and lots and lots and lots of text", "Lots and lots and lots and lots of text", "Lots and lots and lots and lots of text"]] ) { dateTime } }

is now

{ trip( obj: { wheelchair: false, smallObj: { a: 1 }, largeObj: { wheelchair: false, smallObj: { a: 1 }, arriveBy: false, includePlannedCancellations: true, transitDistanceReluctance: 2000, anotherLongFieldName: "Lots and lots and lots and lots of text" }, arriveBy: false, includePlannedCancellations: true, transitDistanceReluctance: 2000, anotherLongFieldName: "Lots and lots and lots and lots of text" } ) { dateTime } another( list: [ ["small array", "small", "small"], [ "Lots and lots and lots and lots of text", "Lots and lots and lots and lots of text", "Lots and lots and lots and lots of text" ] ] ) { dateTime } }

I agree that #2797 (comment) would be a better long term approach but rewriting the printer to support something like the prettier document builder with softlines and length aware line breaks is a much larger effort. This change will allow lines greater than 80 but it at least gives us a reasonable default for when to break out these larger lines.

@dylanowen Thanks for PR!
I changed it to match both spec examples and prettier output (removed commas)
Also I changed a code to match existing solution for args from #2797
