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.

**Description:**

This PR splits the `MultiReplacer` into two variants. The first one is the cloning version, and this is parallel. The other one is the non-cloning version, which is not parallel.

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.
