Add generic IO-APIC support to chipset resources

[moor-coding]

• Move IoApicRouting trait to chipset_resources crate with re-export
• Add IoApicRoutingHandleKind resource kind and GenericIoApicDeviceHandle
• Add async resolver that registers line interrupt targets
• Add IoApicRoutingResolver platform resolver in vmm_core
• Make num_entries constant (IOAPIC_NUM_ENTRIES = 24)
• Remove GenericIoApicDeps from base_chipset macro and workers

Pull request overview

This PR refactors generic IO-APIC support to be resource/resolver-driven by moving IO-APIC routing into chipset_resources and wiring platform-specific routing via platform resolvers, eliminating the old GenericIoApicDeps plumbing in the base chipset builder.

Changes:

• Introduces chipset_resources::ioapic (routing trait + handle kinds + GenericIoApicDeviceHandle) and a chipset::ioapic::resolver::GenericIoApicResolver.
• Updates manifest building to attach a generic IO-APIC device handle (and sets capabilities.with_ioapic) instead of using legacy with_generic_ioapic/deps wiring.
• Registers the new chipset resolver and adds a platform resolver (IoApicRoutingResolver) in both OpenVMM and Underhill workers.

vm/devices/chipset/src/ioapic/mod.rs:29

• use std::fmt::Debug; appears to be unused now that the local IoApicRouting trait (and its Debug impl) was removed in favor of chipset_resources::ioapic::IoApicRouting. With warnings denied in CI, this unused import will fail the build; please remove it (or reference it explicitly if still needed).
