Support Typescript 5

Execute tns info e inspecione o package.json do projeto para confirmar as versões Angular 16, TypeScript 5 e TSLib 2.5. Reproduza a falha usando uma activity personalizada conforme descrito na documentação do NativeScript; considera-se concluído quando o app inicia normalmente e a activity personalizada pode ser usada sem o erro class-not-found relatado.

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• NativeScript-Angular: 16
• Angular: 16

Describe the bug
Using Angular 16 which uses Typescript 5 and updated TSLib renders custom activities unusable and does not allow the app to start. Refer to this chat
