CI jobs: upgrade CVC5 from 1.0.0 to 1.1.2

[tautschnig]

Since version 1.0.1, CVC5 also releases a binary for macOS ARM, which will enable CBMC CI runs on that platform (see
#8382). More recent releases of CVC5, however, have also moved to releasing zip archives rather than single binaries. This necessitates an overhaul of the rules to download and install CVC5 beyond just changing the version number.
