[lworld] RFR: 8376042: [lworld] Revert changes to --patch-module handling [v3]

[Matias Saavedra Silva]

> Migrated value classes were previously handled with `--patch-module` and lworld-specific changes were added to better handle the new use case. Now that jimage is used instead, we can remove these special checks and refactors to better align lworld with mainline. Verified with tier1-5 tests.
