Similar to #57229, this commit ensures that `Compiler.finish!` properly synchronizes the operations to set `max_world` for cached `CodeInstance`s by holding the world counter lock. Previously, `Compiler.finish!` relied on a narrow timing window to avoid race conditions, which was not a robust approach in a concurrent execution environment. This change ensures that `Compiler.finish!` holds the appropriate lock (via `jl_promote_ci_to_current`).
