[FEA] Report solver version / hash in the log

[aliceb-nv]

Most other solvers like SCIP/Highs/Gurobi report the version of the solver used in their logs, along with some extra information such as build date or commit hash.

Furthermore, so far users have no way of printing the version of cuOpt they are using. Adding such information to the logs is also important for benchmarking and result reporting purposes.

Possible output format:

cuOpt optimization solver, version 25.10 (arch: <arch>, build hash <hash>)
CPU Model: <model>, Host memory: <RAM>
Thread count: <threads>
GPU Model: <model>, Device memory: <VRAM>
