feat(es/minifier): Ignore return values of ignored IIFEs (#6020) 
**Description:**

As we are not using the return value of the function, we can call `ignore_return_value` on the argument of the return statements of IIFE.

feat(es/minifier): Inline lazily initialized variables (#5737) 
Safety:

For a function-local variable, an expression with side-effects would be a call, including an indirect one with a member expression.

 - If the call is function-local, it will be analyzed by the analyzer and inliner will not work.
 - If the call is not a function-local one, it cannot modify the local variable.
