test(windows-drivers): CI-assert the full IddCx driver symbol surface

Port-plan critique #1: convert "the (?i).*iddcx.* allowlist may miss a symbol the
full driver needs" from a box-only surprise into a CI compile gate. New
wdk-probe/src/iddcx_surface_assert.rs size_of-asserts every *2/HDR struct
(IDDCX_TARGET_MODE2/PATH2/METADATA2, IDARG_*RELEASEANDACQUIREBUFFER2 — these embed
DISPLAYCONFIG_*/LUID, which RESOLVE from crate::types: no allowlist gap),
None-asserts all 14 inbound PFN_IDD_CX_* callbacks, and confirms the .Size
machinery (IddStructures/IddStructureCount/IddClientVersionHigherThanFramework/
_IDDSTRUCTENUM::INDEX_*) + the FP16/HIGH_COLOR_SPACE flags. Box-built green; the
wdk-sys binding is proven complete for the ENTIRE driver, not just init. Also
silence the bindgen naming lints in the iddcx module.
