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.
