[feature] JSON output for conan profile show

[p-groarke]

What is your suggestion?

Along the lines of #5937

It would be swell if we could output a conan profile as a json formatted object. conan profile show --format json my-amazing-profile-unicorns

We use conan profiles to drive our build matrices, which mean we end up converting them manually in many places to interact with other pipeline systems. It would also allow easy parsing in cmake (which can parse json natively).

The addition would help conan profiles be our "single source of truth", enabling consumption in virtually any language out there. Obviously this isn't pressing, just a nice to have :]
