Simplify CI workflow and actions

[ia0]

We don't run all checks when building the cache anymore.

This pull request simplifies the CI workflow by refactoring the ci-checks action to handle a single check at a time instead of a list of checks. This removes the need for JSON parsing and simplifies the conditional logic for running steps. The consolidation of tests-* jobs into a single dynamic step is a good improvement. However, I've found a critical issue: a recurring typo in the action file where input.check is used instead of inputs.check. This will prevent most of the checks from running. Please see my detailed comment for a suggested fix.

This pull request simplifies the ci-checks GitHub Action by changing its input from a list of checks to a single check. This significantly improves the readability and maintainability of the workflow by replacing complex contains(fromJSON(...)) expressions with simple string comparisons. The consolidation of the sharded test steps into a single dynamic step is a particularly nice improvement. The related ci-footprint action is also simplified. Overall, these are great changes. I have one minor suggestion to make the test sharding logic even cleaner by using a built-in GitHub Actions function.

This pull request simplifies the CI workflow by refactoring the ci-checks action to handle a single check per invocation instead of a list of checks. This is a great improvement that will likely allow for better parallelization and clearer job definitions in the calling workflows. The removal of the use-cache input and related logic in both ci-checks and ci-footprint actions further streamlines the implementation. The changes are well-executed and improve the maintainability of the CI configuration. I have one minor suggestion to improve the readability of a condition.
