Fix IOAPIC/HPET/NMI, PS/2 driver, and remove duplicate VT service entries

- IOAPIC: enable full IOAPIC initialization on AMD/Intel bare metal, dual GSI 0/2 timer mapping for platform compatibility, NMI handler uses raw COM1 PIO writes to avoid mutex deadlock - HPET: counter validation, graceful fallback to PIT when HPET missing - PS/2: fix 0xFE RESEND handling in all MouseState variants, add controller flush/self-test retry/aux port test from Linux 7.0 - ACPI: defer AML evaluation to avoid blocking initfs driver spawn - VT chain: remove duplicate rootfs service files (inputd, vesad, fbcond, getty) that were already handled by initfs phase 1 and the legacy 30_console script from minimal.toml - QEMU verified: boots to login prompt, 20 rootfs units (was 26), single login prompt (was double), only 1 expected error (wifictl)

+Defer AML initialization until PCI registration completes.
+
+When acpid starts before pcid has registered the PCI fd, AML
+initialization fails with a misleading ERROR-level message. This is
+expected on every boot because the service ordering requires acpid to
+start before pcid-spawner. The AML interpreter initializes successfully
+after pcid registers via /scheme/acpi/register_pci.
+
+Changes:
+- aml_context_mut(): log at DEBUG instead of ERROR when PCI fd is None
+  (expected pre-registration state, not a fault)
+- Fadt::init(): skip \\_S5 evaluation when PCI is not yet registered,
+  since refresh_s5_values() is retried in register_pci_fd() after PCI
+  registration completes
