First step of the device-code reorganization (plan: group device code by
domain, split each domain into a shareable data module + a logic module).
This moves the pure-data modules — the enums, wire types, and taxonomies
that any layer including the kernel can import cheaply — out of
system/devices/ and into their domain home:
device-abi -> library/device/model/device-abi.zig
pci-class -> library/device/pci/pci-class.zig
usb-abi -> library/device/usb/usb-abi.zig
usb-ids -> library/device/usb/usb-ids.zig
acpi-ids -> library/device/acpi/acpi-ids.zig
aml/ -> library/device/acpi/aml/
Module names are unchanged, so this is a pure file move: only the
b.addModule paths and the host-test file list in build.zig change; no
importer is touched. system/devices/ now holds only the kernel-internal
device model (device-model, platform, acpi, device-tree, power).
The device *logic* (the pci Function helper, the usb transfer client) and
the kernel's cosmetic taxonomy dependency are handled in following commits.
zig build + zig build test green.
