Description of changes

A cycle is seen with compiling the iOS FluentUILib during copy build phase for the modulemap.

[2022/09/29.17:49:50] Error: Cycle details:

[2022/09/29.17:49:50] Error: → Target 'FluentUILib' has copy command from '.../fluentui_apple/ios/FluentUI/Core/module.modulemap' to .../Debug/build/tmp/FluentUI/Debug-iphonesimulator/include/FluentUI/module.modulemap'

[2022/09/29.17:49:50] Error: ○ Target 'FluentUILib' has Swift tasks blocking downstream compilation

[2022/09/29.17:49:50] STDERR: ** BUILD FAILED **

To fix this, I am following Apple's suggestion of moving the copy build phase before the compilation build phase.

Verification

• Unable to repro the cycle with the fix in place in the FluentUI demo project
