Skip EnsureCodeFixesProjectBuilt target when NoBuild=true

dotnet pack --no-build sets NoBuild=true, which prohibits invoking the
Build target. The custom EnsureCodeFixesProjectBuilt target was doing
exactly that, triggering NETSDK1085. Adding the condition makes the
target a no-op when the caller has already asserted everything is built.

Fix build issues introduced by recent package upgrades

- Add Microsoft.Build.Framework 18.4.0 with ExcludeAssets=runtime/PrivateAssets=all
  to Directory.Packages.props and Integration.Tests project to resolve MSBL001 error
  introduced by Microsoft.Build.Locator 1.11.2

- Change GuidelineXmlToMD.Test to target net10.0 only (matching the tool project's
  TargetFramework) to fix NU1201 TFM compatibility restore errors

- Fix pre-existing nullable reference errors now surfaced in Tools build:
  - GuidelineXmlFileReader.cs: null-check Root before iterating, use ?? for attributes
  - MdExtensions.cs: remove unnecessary ?. on already-validated str parameter
  - MdText.cs: use ?? string.Empty for ToString() nullable return
  - GuidelineXmlFileReaderTest.cs: add ! null-forgiving on Directory.GetParent chain
