Can't build binding projects without a Mac connection

[rolfbjarne]

Building a binding project from Windows doesn't work unless the build is connected to a Mac.

Ref:

• MAUI/net6 - could not compile IOS native binding project - Access to the path is denied. #15981

We should look into fixing this, or notify the user that it doesn't work (either through a warning or an error) if we can't fix it.

This is a duplicate of #16611.
