target/i386/sev: Move qmp_sev_inject_launch_secret() to sev.c

Move qmp_sev_inject_launch_secret() from monitor.c to sev.c
and make sev_inject_launch_secret() static. We don't need the
stub anymore, remove it.

Previously with binaries built without SEV, management layer
was getting an empty response:

  { "execute": "sev-inject-launch-secret",
    "arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa": 4294959104 }
  }
  {
      "return": {
      }
  }

Now the response is explicit, mentioning the feature is disabled:

  { "execute": "sev-inject-launch-secret",
          "arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa": 4294959104 }
  }
  {
      "error": {
          "class": "GenericError",
          "desc": "this feature or command is not currently supported"
      }
  }
