[CONUTILS]

[CONUTILS]
- Introduce new functionalities related to console streams, a console screen management api (almost stubbed), a console pager api (adapted from code from CMD). This new functionality will be used in the future. See CORE-10504 for more details.
- As this library is therefore growing up, split it in small parts (sublibraries) that can be used, with the following dependency scheme: base utils (standalone); streams depending on base; screen depending on streams; pager depending on screen.

[APPS]: As a result, modify the CMakeLists of the different apps that use conutils to make them depend on the correct sublibrary.
