api: vat2 and json autogeneration for api messages

VAT2: A completely auto-generated replacement of VAT.
Reads input message in JSON from stdin and outputs received messages in JSON.

A VAT2 plugin is automatically built for a .api file.
There no longer a need for a separate _test.c.

Example:
vat2 show_version {}
{
        "_msgname":     "show_version_reply",
        "retval":       0,
        "program":      "vpe",
        "version":      "21.01-rc0~411-gf6eb348a6",
        "build_date":   "2020-11-19T09:49:25",
        "build_directory":      "/vpp/autogen3"
}

vat2 sw_interface_dump '{"sw_if_index": -1,
                         "name_filter_valid": 0,
                         "name_filter": ""}'

        }]

This is the first phase and vat2 is not integrated in packaging yet.
