ix(4): Add support for debug dump for E610 adapters

This is part 2 of the support for the new Intel Ethernet E610 family of devices.

Intel E610 Ethernet Controller devices feature a debug dump capability
that allows you to capture runtime register values directly from the
hardware, with assistance from the firmware. These registers are
organized into clusters based on their function, enabling targeted
debugging. This information is consolidated into a single dump file,
facilitating the debugging of complex issues encountered in the field.
The debug dump provides a snapshot of the device's current hardware
configuration, including switch tables, transmit scheduler tables, and
other relevant data. It captures the state of specified clusters and
serves as a stateless snapshot of the entire device.

This update introduces ioctl and sysctl support for the debug dump feature.
