[MOB-9980] Add sync_generated_files CI Job (#749)

* Add CI Job `validate_changes`

* Rename to `validate_sync`

* Ignore EXCLUDED_ARCHS Changes

These type of change needs to be ignored because it's machine-dependant.
Running the same command on macOS with different architectures, will
make changes in `project.pbxproj` in the following line:

    "EXCLUDED_ARCHS[sdk=iphonesimulator*]" = "arm64";
    "EXCLUDED_ARCHS[sdk=iphonesimulator*]" = "";

* Rename to `sync_generated_files`
