[ios] switch cross32/crosswatch to be executed on x86_64 and use newer LLVM (#14852)

Fixes https://github.com/mono/mono/issues/14841

Note that it breaks iOS 32bit on devices. The Apple Watch _might_ still works (only tested on `2019-02`).  It unblocks some build related issues on the Xamarin.iOS `2019-06` integration, and we have to do it anyway. I'll come back to it to fix device related issues.
