fix(es/minifier): don't eliminate class expr if some side effects contain this

[CPunisher]

Description:

Manual reasoning:

Um...There are some options to handle this problem:

1. Prefer size. Check if there's any this in the statement with side effect. This could be inefficient and I'm not sure whether there's any other corner case.
2. Prefer performance. Just like what oxc does, keep entire class declarations if some static property contains side effect initializer.

Since it's anti-pattern code, I'm not sure above options are worthy just for this case...Maybe a better one is emitting warnings for all those anti-pattern code. However, swc minifier doesn't diagnostic system for minifier, and I don't know how many code in swc minifier is used for handling such cases (so it could be redundant to introduce it now).

After some consideration I finally decide to directly add contains_this_expr check for it.
