QDicts are both what QMP natively uses and what the keyval parser
produces. Going through QemuOpts isn't useful for either one, so switch
the main device creation function to QDicts. By sharing more code with
the -object/object-add code path, we can even reduce the code size a
bit.
This commit doesn't remove the detour through QemuOpts from any code
path yet, but it allows the following commits to do so.

Thank you to have added the errp pointer in the hide_device helpers, it helps in my series.
