[Bug 265223] libxo json output for ps uses strings for numeric properties

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=265223

            Bug ID: 265223
           Summary: libxo json output for ps uses strings for numeric
                    properties
           Product: Base System
           Version: 13.1-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: bugs@FreeBSD.org
          Reporter: wes@wezm.net

It seems that all the properties that are collected for output in `ps` are
stringified in format_output[1]. As a result values that are numeric end up as
strings in the libxo json output. E.g.

$ ps --libxo json,pretty -o pid,command,pcpu
{
  "process-information": {
    "process": [
      {
        "pid": "30811",
        "command": "-sh (sh)",
        "percent-cpu": "0.0"
      },
      {
        "pid": "30816",
        "command": "ps --libxo json,",
        "percent-cpu": "0.0"
      },
      {
        "pid": "16796",
        "command": "./mqttd",
        "percent-cpu": "0.0"
      }
    ]
  }
}

The expected behaviour in this example would be for `pid` and `percent-cpu` to
be JSON numbers (although this issue is not limited to just these fields). I.e.

      {
        "pid": 16796,
        "command": "./mqttd",
        "percent-cpu": 0.0
      }

For comparison I note that the libxo output of `df` does use the correct types:

      {
        "name": "zroot/usr/src",
        "total-blocks": 24195196,
        "used-blocks": 96,
        "available-blocks": 24195100,
        "used-percent": 0,
        "mounted-on": "/usr/src"
      },
