Validate target names passed to build_examples.py (#24644)

* Validate target names passed to build_examples.py

Skipping invalid target names might lead to false positive CI passes in
case when target name is invalid. In such case test was never executed.

* Fix target names for Tizen examples CI checks

* Restyled by isort

* Add libwebsockets submodule to Tizen platform
