cant disable multidex

because of that line https://github.com/NativeScript/android-runtime/blob/master/build-artifacts/project-template-gradle/app/src/main/java/com/tns/NativeScriptApplication.java#L32 a user cant decide to disable multidex if possible (would make app smaller).
The reason is that without multidex enabled that line would not compile. I tried a few things but it is a bit tricky to do preprocessor through gradle 7.0 (plugins not working anymore).
The idea would be to use a preprocessor to get rid of the line at compilation if multidex is disabled

从 build-artifacts/project-template-gradle/app/src/main/java/com/tns/NativeScriptApplication.java 的第 32 行开始，检查 Gradle 7.0 项目模板如何启用 multidex。确定在禁用 multidex 时如何排除该行，然后验证启用和禁用 multidex 的配置都能编译，并且禁用 multidex 的配置会生成更小的应用。
