[Task]: Eliminate `ClassLoadingStrategy.Default.INJECTION` throughout Beam Java code base

[Abacn]

What needs to happen?

Past works: #25578 #26508

ClassLoadingStrategy.Default.INJECTION requires the access to jdk internal API, which is discouraged and needs to explicit --add-opens jvm options in Java16+.

Current workaround is to add --jdkAddOpenModules=java.base/java.lang=ALL-UNNAMED to the pipeline option. However, we should clean up the remaining usages.
