[736] Make the bundled xtable-utilities jar runnable again (Hudi 0.x) + CI on branch-0.4 (#841)

* [736] Make the bundled xtable-utilities jar runnable again (Hudi 0.x)

Cherry-pick of #840 (4daec27) adapted for the Hudi 0.14 line on
main-hudi-0x. The #736 root cause applies here too: the #822 shade
allowlist dropped runtime deps from the bundled utilities jar, so
java -jar RunSync failed with NoClassDefFoundError.

Applicable subset for Hudi 0.x:
- jol-core: the parent pins it to test scope, but Hudi's
  ObjectSizeCalculator loads org.openjdk.jol at runtime; override to
  runtime and add to the shade allowlist (the actual #736 fix).
- slf4j-api: add to the allowlist (org/slf4j/LoggerFactory was missing).

Dropped from the original #840 (Hudi 1.x only): hudi-hadoop-common and
hudi-io do not exist in Hudi 0.14 (that split is 1.x); hudi-common still
provides org.apache.hudi.common.fs.FSUtils. There is also no redundant
test-scoped hudi-java-client to remove on this branch.

Verified: the 0.x bundled jar now contains org/slf4j/LoggerFactory,
org/openjdk/jol/info/GraphLayout, org/apache/hudi/common/fs/FSUtils and
org/apache/hudi/client/common/HoodieJavaEngineContext.

Cherry picked from commit 4daec27.

* ci: run Maven CI build and license check on main-hudi-0x

Add main-hudi-0x to the push and pull_request branch triggers so the
existing CI (build + test, license check) runs for the long-lived
Hudi 0.x branch and PRs targeting it, matching main. package-deploy
(release-triggered) and the site workflows are unchanged.

The concurrency guard already treats any ref containing "main" as
non-cancelable, so main-hudi-0x is covered without further changes.

* ci: point branch triggers at branch-0.4 (renamed from main-hudi-0x)

The release branch was renamed main-hudi-0x -> branch-0.4 to use a
version-keyed name instead of a dependency-keyed one. Update the push /
pull_request triggers so Maven CI Build and License Check run on the
renamed branch.
