Revert "Support single line objects and arrays"

This reverts commit 6a7d56fa0f7009be9df36774774f3c337d7c7760.

Reason for revert: Earlier commit needs to be reverted for Chrome roll.

Original change's description:
> Support single line objects and arrays
> 
> This is just a formatting nicety. The new caps dump has several large
> arrays of structs, and keeping each object on one line makes them much
> more readable. (It also limits the total length of the output, which
> helps when scanning through).
> 
> Example of the output, before and after this change:
> https://gist.github.com/brianosman/872f33be9af49031023b791e7db0b1fb
