Summary of Changes

Hello @scotthart, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates the Dockerfiles used in the CI pipeline to reflect current library versions and dependency requirements. The primary changes involve upgrading the Abseil-cpp library to a newer release and completely removing the crc32c library as a direct dependency, simplifying the build configurations across various Linux distributions. These updates aim to maintain compatibility, leverage newer library features, and optimize the CI build environments.

Highlights

• Abseil-cpp Version Update: The Abseil-cpp library has been updated to version 20250814.1 across most Dockerfiles, ensuring the use of the latest features and fixes.
• CRC32c Dependency Removal: The crc32c library has been entirely removed from both package manager installations and source builds across all affected Dockerfiles, streamlining the build process and reducing dependencies.
• CMake Flag Refinement: The ABSL_PROPAGATE_CXX_STD=ON CMake flag has been removed from Abseil-cpp builds in several Dockerfiles, indicating a simplification or update in how C++ standard propagation is handled by the newer Abseil versions.

Code Review

This pull request updates the Dockerfiles used in CI, primarily focusing on updating the Abseil C++ library version and streamlining dependency installations. The Abseil library is updated to 20250814.1 across all Dockerfiles where it's built from source. Additionally, the ABSL_PROPAGATE_CXX_STD=ON CMake flag has been removed from Abseil builds, and in some cases, -DCMAKE_CXX_STANDARD=17 is explicitly added. A significant change is the consistent removal of crc32c installation or build steps from almost all Dockerfiles.
