[MINOR][4.X][INFRA] Run post-merge Build every ten commits
### What changes were proposed in this pull request?
Apply the commit-count gating pattern from #57555 to the branch-4.x copy of
.github/workflows/build_main.yml.
The workflow checks out the full pushed branch history and counts its
commits. Builds on forks continue to run for every push, while post-merge Build
runs on apache/spark run when the commit count is divisible by ten.
### Why are the changes needed?
Post-merge Build runs on branch-4.x are currently disabled completely to
save CI resources. Running the workflow every ten commits restores periodic
validation while retaining most of those resource savings.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Ran git diff --check and reviewed the workflow diff against the pattern in
#57555.
No runtime tests were run because this change modifies only GitHub Actions
orchestration.
### Was this patch authored or co-authored using generative AI tooling?

Closes #57841 from zhengruifeng/build-branch-4.x-every-ten-commits-dev1.
