ci(windows-drivers): dump generated iddcx.rs structure on failure (diagnostic)

UINT fails to resolve despite a top-level `pub type UINT` in the same scope as the
working `use crate::types::*` — error count byte-identical before/after the fix.
Add an if:always() step dumping the generated module structure + UINT-use context
to pinpoint the scope mismatch (RTX box rebooted to Proxmox, so CI is the only
validator).
