fix(es/minifier): Fix ordering issue of analyzer (#6150) 
**Description:**

This is the groundwork for a parallel analyzer. This PR fixes the ordering issue of the analyzer so that the analyzer works identically regardless of the visit order. This patch contains some improvements because previously, we mixed `.and_modify()` and `.or_default()`.

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.

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.
