Enabled the creation of EXEs via Inno Setup

[jmjaffe37]

Hello! Microsoft recently made the decision to start transitioning our Windows installers from MSI to EXE. This decision was made to accommodate a more modern user experience that is user-friendly, fully accessible, and easily customized. The tool Inno Setup is used to create these EXEs.

Microsoft has already published these EXEs for the October-2025 release. You can find them on our downloads page. For your convenience, I will also provide a direct download link to our latest, live OpenJDK 25 EXE here (Note: this link is for an x64 installation).
