Work around a problem where our MSI version is unconveniently correct: some
time ago we fixed a bug where the MSI version was wildly incorrect, but the
side effect is that now our MSI version is lower than the last MSI version
inserted into VS.

So come up with a versioning scheme that ends up with an MSI version that's
higher than the last MSI version inserted into VS.

…serted MSI version.

Pull request overview

This PR implements a workaround for an MSI versioning issue specific to .NET 10. Previously, a bug fix corrected wildly incorrect MSI versions, but as a side effect, the new correct versions are now lower than the last MSI version inserted into Visual Studio (255.220.39248). Since VS cannot accept lower MSI versions, the PR introduces a custom versioning scheme for .NET 10 that generates MSI versions higher than the problematic minimum.

Key Changes:

  • Adds Xcode version-based calculation for MSI minor version bumps
  • Introduces per-platform commit distance tracking in the version calculation
  • Adds validation logic to apply custom versioning only for .NET 10 (not needed for .NET 11+)
