scripts: Add qom-tree script
Functionally it is a recursive qom-list with qom-get per non-child<> property. Some failures needed to be handled, such as trying to read a pointer property, which is not representable in QMP. Those print a literal "<EXCEPTION>". Tested-by: Alistair Francis <alistair.francis@xilinx.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
