Add cuOpt to unified devcontainers

[bdice]

This adds cuOpt to the unified devcontainers. It releases on the same cadence as RAPIDS and has RAPIDS dependency infrastructure, so it's useful to be able to do test builds of cuOpt in a RAPIDS environments.

Depends on:

• Remove alpha specs from non-RAPIDS dependencies NVIDIA/cuopt#660
• Create separate test run scripts NVIDIA/cuopt#722
• Modernize dependency pinnings NVIDIA/cuopt#723
• Use static GTest NVIDIA/cuopt#729
