Fix stampinf, ApiValidator, and Dvl.exe failures in CI tests

- Remove <Inf> items from KMDFTestTemplate.vcxproj and CppKMDFTestTemplate.vcxproj
  so the StampInf MSBuild task is not triggered (stampinf.exe is not available in
  a NuGet-only WDK environment).  These templates exist solely for CodeQL analysis,
  not for building a production driver, so INF stamping is not needed.

- Add <ApiValidatorEnabled>false</ApiValidatorEnabled> to Directory.Build.props.
  ApiValidator.exe is not included in the WDK NuGet packages and is not available
  in the CI environment.  Disabling it allows the ApplicationForDriversTestTemplate
  (WindowsApplicationForDrivers10.0 toolset) to compile successfully for CodeQL.

- Update dvl_tests.ps1 to locate Dvl.exe dynamically from the NuGet packages
  directory instead of assuming the traditional system WDK install path
  C:\Program Files (x86)\Windows Kits\10\Tools\dvl\Dvl.exe.  Falls back to the
  system path for developer machines with a full WDK install, and gracefully skips
  the dvl command-type tests when Dvl.exe is not found in either location.

- Fix typo -test_emtpy -> -test_empty in the second Test-DVL "dvl" call inside
  Test-Driver (the typo was previously unreachable because the test exited earlier
  due to the Dvl.exe failure).
