Subject: info: Add JSON output

Output JSON with the --json=v1 option. Output is in an array, and
supports one or more formulae (or all, with the --all option).

Why 'v1'? The format is unstable, presumably we'll deprecate it
someday. It should be solid by Homebrew 1.0.

Closes Homebrew/homebrew#13299.---
