Pull request overview

Adds detection and reporting when a solution/context ends up selecting multiple versions of the same pack, improving visibility into conflicting pack requirements.

Changes:

• Emit a warning during pack filtering if more than one version of the same pack is selected for a context.
• Add a unit test asserting the warning is produced.
• Add a new .csolution.yml test input that selects two versions of ARM::RteTest_DFP (one by version, one via path).
