[PATCH pve-manager] ui: qemu: HDEdit: add iothread-vq-mapping UI controls

[Dominik Budzowski]

Add a 'VQ Mapping' checkbox and 'VQ count' integer field (2-16) to the
hard disk edit panel. When VQ Mapping is enabled, the standard IO thread
checkbox is disabled (they are mutually exclusive), and the selected count
is stored as iothread_vq_mapping on the drive config.

Loading an existing drive with iothread_vq_mapping set pre-selects the
VQ Mapping checkbox and restores the count value.
