Add v80-smi static shell flashing

[amd-vserbu]

Summary

• Adds v80-smi write-static-shell so users can program the V80 static shell from packaged shell assets or an explicit PDI.
• Extends vrtd with authorized cfgmem programming, async progress reporting, and hotplug coordination for reliable flash updates.
• Packages the Vivado flashing helper and documents the new static shell programming workflow.

Usage

This PR enables:

v80-smi write-static-shell --flash --device <BDF>

or

v80-smi write-static-shell --jtag --device <BDF>
# or
v80-smi write-static-shell --jtag --no-remove-device

For jtag, the BDF is only required to remove the device from the daemon and kernel current devices list before reprogramming. For shells programmed for the first time, --no-remove-device is appropriate. If multiple devices are connected via jtag, you can/must specify a particular xsdb device_id with --xsdb-target-id.

By default, this writes the static shell from slashkit. You can specify a specific shell with --pdi.

This also allows bootstrapping without writing AVED from the Vivado GUI.

There are also no more reboots needed after writing the image.
