Integrate ctcache to improve build time in industrial_ci

[ipa-rar]

Context
When using clang-tidy as part of the ROS build pipeline, the analysis phase can be quite time-consuming, especially for large C++ packages. Re-running clang-tidy on previously analyzed code can lead to unnecessary overhead and delays. ctcache addresses this by caching results and reusing them for unchanged files.

In our use case, integrating ctcache locally has resulted in a notable reduction in build time by avoiding redundant static analysis operations. This improvement would be beneficial for many users who run industrial_ci in CI environments where build speed is critical.

Feature Request
I'd like to suggest adding support for ctcache to industrial_ci. ctcache significantly improves build times by caching static analysis results from clang-tidy, avoiding repeated analysis of unchanged files.

Discussion
I believe this feature could greatly enhance the efficiency of the industrial_ci pipeline. I would like to hear from the maintainers and the community—would this be a useful addition for others as well? Are there any potential challenges or concerns with adding ctcache support to industrial_ci?
