Andreas Kling 141063e91d LibJS: Precompile top-level IIFEs off-thread ...

Mark direct calls to function expressions while generating top-level
Rust bytecode, then compile those functions before returning the
off-thread compilation result to WebContent.

The main thread still performs all VM and GC-backed materialization. It
now receives an already assembled executable for each eager IIFE and
attaches it to the SharedFunctionInstanceData while creating the parent
Executable. Nested functions owned by the eager executable remain lazy.

This targets large wrapper IIFEs that are invoked as soon as top-level
code starts running. Their bytecode generation now runs on the existing
script compilation worker instead of blocking the main thread on first
call.
