When trying to analyze the compilation caching behavior on apache#51255, I realized that our maximum ccache size of 1GB had become too small for some builds. The result is that a single build cannot be cached in its entirety, making identical rebuilds costlier than they should be.

Rationale for this change
The
test-ubuntu-24.04-cpp-bundled-offlineCrossbow job usually takes one hour to complete:https://github.com/ursacomputing/crossbow/actions/runs/34175056969/job/101902703505
This is because, despite sccache being configured, the S3-stored compilation cache is unavailable because the network is shut off during compilation. And the job compiles all dependencies from scratch.
What changes are included in this PR?
Move the CI job to the C++ Extra workflow, so as to take advantage of ccache-based compilation caching using
apache/infrastructure-actions/stash.Are these changes tested?
By definition, yes.
Are there any user-facing changes?
No.
