[CI] Build built-in libraries

Since {whole-archive} option has been removed the CI is not fully relevant. So need to explicitly used basic functions of the built-in library. The arduino-cli script have been updated to handle properly region overflowed which is not a real issue while there is no other issue. Signed-off-by: Frederic Pillon <frederic.pillon@st.com>
