The functionality of -writeconfig is limited and the code
does not even try to detect cases where it prints incorrect
syntax (for example if values have a quote in them, since
qemu_config_parse does not support any kind of escaping)
so remove it.

I'd suggest same here too

Can we hide/remove it from qemu-options.hx, while still letting it be
used if people know it exists ? Failing that, at least add the deprecation
note to the qemu-options.hx help text
