Remove Ubuntu 20 and RHEL/Rocky 8 support, increase cmake min version

Ubuntu 20 is EOL [1]. This was the version with the lowest CMake version, so
we can increment the minimum CMake version to 3.19 as well. Increasing the
minimum version will in particular help with the integration of CUDA (updates
in 3.17 and 3.18), the current 3.19 brings better support for apple silicon.

Some minor CMake updates (removing superfluous files and dependencies).
