Brad King 66f49d1f9a Android: Add clang --target= flag to compiler predefines command
When we set `CMAKE_<LANG>_COMPILER_TARGET` to the Android target
architecture, add it to `CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND` also.
This is needed to make moc predefines aware of `__ANDROID__`.

Fixes: #18425
