feat(es/minifier): Clone trivial literals in sequential inliner (#6005)
**Description:**

As our minifier is two-pass by default, this is enough.

At the first pass, we inline all numeric literals using sequential inliner, and minifier can then inline constants correctly in the second pass.

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.

fix(es/minifier): Fix analysis of parameters (#5954)
**Description:**

Although the author of the issue talked about `@react-pdf/renderer`, it's a bug related to `brotli`, not react pdf renderer.

After investigation, I found that the bug is caused by not marking parameters as initialized. So I fixed the analyzer.

fix(es/minifier): Don't replace parameters of IIFE if it's recursive (#5852)

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.
