or-tools: enable SCIP support 

This adds a new argument, withScip, defaulting to true, which will
configure or-tools with SCIP support.

or-tools usually is built with SCIP support, and only tested like this,
see https://github.com/google/or-tools/pull/4745.

However, SCIP only was introduced to nixpkgs March 2025, that's probably
why or-tools in nixpkgs came without it so far.

If built with SCIP support, we need to propagate scip itself, otherwise
downstream cmake consumers need to set SCIP_ROOT explicitly.
