monitor/hmp: rename device-hotplug.c to block/monitor/block-hmp-cmds.c

These days device-hotplug.c only contains the hmp_drive_add
In the next patch, rest of hmp_drive* functions will be moved
there.

Also add block-hmp-cmds.h to contain prototypes of these
functions

License for block-hmp-cmds.h since it contains the code
moved from sysemu.h which lacks license and thus according
to LICENSE is under GPLv2+
