[CALCITE-7649] Add bytecode verification check using ASM in the gradle build

[thomasrebele]

This is a rebase of @zabetak's PR #3783. I've fixed some warnings by adapting AsmCheckerTask to Gradle 8. I had to exclude spark/build/sparkServer/classes, as the classes in that dir failed the check.

I've verified the functionality by building a183b26 (i.e., without the fix for the invalid bytecode of CALCITE-6393) with JDK8. As expected, it produces java.lang.RuntimeException: Invalid bytecode file:/home/trebele/dev/calcite/c1/core/build/classes/java/main/org/apache/calcite/runtime/SqlFunctions.class when running ./gradlew build. The build passes with JDK17 and JDK21.

Here the versions that I've used:

$ /usr/lib/jvm/java-8-openjdk-amd64/bin/java -version
openjdk version "1.8.0_492"
OpenJDK Runtime Environment (build 1.8.0_492-8u492-ga~us2-0ubuntu1~24.04.1-b09)

$ /usr/lib/jvm/java-17-openjdk-amd64/bin/java -version

$ /usr/lib/jvm/java-21-openjdk-amd64/bin/java -version
openjdk version "21.0.11" 2026-04-21
