[PATCH v2 17/27] monitor: Make Xen emulation commands generic ones

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

In order to build hmp-commands.hx once we need to stop using
device target-specific check. Use the generic pattern to make
the command available on all targets, providing a stub with
kind error message when the feature is not available.
