Cheviiot 8551d7fe99 Add Windows Driver Kit (WDK) support for building KMDF/UMDF drivers
download --with-wdk fetches the WDK headers/libs/host-tools NuGet
packages (nuget.org has no vsman-manifest entry for this content) and
lays them out where the DriverKit.BuildTools PlatformToolset expects
them. msbuildEnv wires WDKContentRoot/WDKBuildFolder through
DisableRegistryUse the same way the SDK/toolset paths already are.

Two WDK-package fixups were needed for a real driver to actually
build under Wine: the bundled build-task assembly is versioned for an
older VisualStudioVersion than ours, and the package ships no x86
host-tools directory at all (only x64/arm64), which StampInf hardcodes
a path to.

Also force TZ=UTC for msbuild invocations: StampInf stamps DriverVer
using the local wall-clock date while Inf2Cat validates it against
UTC "now", so any timezone east of UTC sees a "postdated DriverVer"
failure for most of the day.

Verified against a real KMDF sample driver (microsoft/Windows-driver-
samples' echo_2): compiles, links, INF stamps and passes Inf2Cat's
signability check with SignMode=off.
