Improved code for supporting multiple Windows versions

[Lej77]

Hi again, I read your comment in my previous PR #92 and supporting multiple Windows versions definitively complicates the code so it makes sense to limit the scope of the project.

Anyway, I made some improvements to the code for supporting multiple Windows versions and I guess you can merge them into the same branch as the other Windows 10 support:

• Added a multiple-windows-versions feature flag without which the code uses the previous approach of only supporting the latest COM interfaces.
  • Nearly no changes were made to the code outside of interfaces.rs (compared to the code in the main branch).
  • Support for multiple Windows versions is done via interfaces_multi.rs which works as a drop in replacement for interfaces.rs when the feature flag is used.
• Support same Windows versions as mzomparelli/VirtualDesktop: C# wrapper for the Virtual Desktop API on Windows 11..
• Minimized work for adding new Windows versions.
  1. Add new module in interfaces_multi.rs
  2. In the new module declare the new COM interfaces.
     • If only the interface ids has changed then we can use the reusable_com_interface macro to easily re-use the interface definitions from a previous version, like in build_22631_3155.rs
  3. If the code in comobjects.rs or the other files uses new methods then add those to the definitions in build_dyn.rs.

DLL Size

I checked the size of the DLL (built in release mode) with and without the multiple-windows-versions feature:

• Multiple Windows versions: 363 KB
• Latest Windows version only: 342 KB

Tests

I also ran all the tests and they did pass on Windows 10 (well, except for the ones using features that weren't supported):
