[SPARK-57108][INFRA] Skip core/utils build matrix entry for unrelated
changes
### What changes were proposed in this pull request?
Splits the `core, unsafe, kvstore, avro, utils, utils-java, network-common,
network-shuffle, repl, launcher, examples, sketch, variant` build matrix entry
in `build_and_test.yml` into two:
- `core, unsafe, kvstore, utils, utils-java, network-common,
network-shuffle, sketch, variant, launcher` — foundational modules under
`common/` (plus `launcher/`) whose only dependency is `tags`.
- `avro, repl, examples` — modules that are transitive dependents of
`sql`/`hive` and naturally need to run when those change.
Adds a new `build-core-utils` precondition (computed via `is-changed.py`
against just the foundational module list) and a matrix `exclude` rule that
drops the first entry when `build-core-utils == 'false'`. The check is opt-out:
missing/unset means run, so periodic full-build workflows that only set
`"build": "true"` continue to run this entry unchanged.
### Why are the changes needed?
Today, any PR that triggers the `build` job runs every matrix entry,
including the foundational core/utils group, even when the PR only touches SQL
or PySpark code. Because `is-changed.py` propagates changes forward (to
dependents), SQL/PySpark changes never make core/utils tests stale, so the
runner spend is wasted.
After this change:
- SQL-only / PySpark-only PR → `build-core-utils=false` → the core/utils
runner is skipped. The `avro, repl, examples` runner still fires because those
modules are transitive dependents of `sql`/`hive`.
- Core/utils PR → `build-core-utils=true` → entry runs as before.
- Periodic full-build workflows (e.g. `build_java21.yml`) → no
`build-core-utils` key, opt-out semantics keeps the entry running.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Validated the workflow YAML parses and that the literal string used in the
`exclude` expression matches the matrix entry string exactly (so the exclude
rule actually fires).
### Was this patch authored or co-authored using generative AI tooling?

Closes #56152 from gengliangwang/infra-skip-core-utils-build.
