[Task] patina_boot: Extend BootOptions to support arbitrary boot devices

[kat-perez]

Description

Extend Config<BootOptions> to support an arbitrary number of boot devices instead of just primary/secondary.

Requirements

• Change from primary/secondary fields to a Vec<DevicePathBuf>
• Support hotkey_devices as alternate boot list when hotkey is pressed
• Maintain builder pattern API

Current State

BootOptions currently only supports:

• primary: Option<DevicePathBuf>
• secondary: Option<DevicePathBuf>

The RFC shows:

devices: vec![
    DevicePath::from("PciRoot(0x0)/Pci(0x1D,0x0)/NVMe(...)"),
    DevicePath::from("PciRoot(0x0)/Pci(0x14,0x0)/USB(...)"),
],
