Corrections included:
1. Changed the test names from debian to ubuntu as it is more stable than Debian Trixie
2. Added explicit compiler in cmake command as GCC compiler below version 14 have been recorded

3. Added dependencies which are not installed by default in the RISC-V Ubuntu 24.04
4. Separate ccache directory for all jobs as all the ccache results are not the same and may cause ccache to not work

* Update ci/run.sh
