Vendor the published, self-contained windows-drivers-rs 0.5.1 crates
(wdk-build, wdk-sys) under vendor/ and add a first-class ApiSubset::Iddcx that
bindgens iddcx/1.10/IddCx.h in an extra pass reusing bindgen::Builder::wdk_default
(allowlist_file (?i).*iddcx.* — emits only IddCx items; WDF/DXGI types resolve to
the shared base/wdf bindings, type-identity by construction). Mirrors the existing
gpio/hid/spb subsets exactly: wdk-build gets the enum variant + iddcx_headers()
(UMDF-only), wdk-sys gets generate_iddcx + the iddcx feature + pub mod iddcx.
[patch.crates-io] redirects all wdk-sys/wdk-build (incl. wdk 0.4.1 transitive) to
the patched copies. wdk-probe enables the iddcx feature.
MAKE-OR-BREAK: does IddCx.h bindgen in wdk-sys config without a header conflict
(issue #515) + does the generated module compile (type-identity)? CI answers it.
