fix(windows-drivers): size_of config size (1.0 IddCxStub lacks the version table) + CI builds pf-vdisplay

The versioned IDD_STRUCTURE_SIZE path referenced IddClientVersionHigherThanFramework/
IddStructureCount/IddStructures — LNK2019 unresolved, because the WDK links the iddcx
1.0 IddCxStub which lacks those (they are >=1.4). We target 1.10 against a current
framework (higher==false) where size_of is exactly the versioned result, so use it
directly (the surface-assert refs linked only because they were DCE-eliminated).
pf-vdisplay now COMPILES + LINKS IddCxStub on the box (263,680B). Point
windows-drivers.yml at the whole workspace + clear FORCE_INTEGRITY on pf_vdisplay.dll;
drop the obsolete UINT diagnostic dump.
