fix(emotion): use swc_css to minify css string

[JSerFeng]

Use swc_css to minify css string in emotion

Use swc_css to minify css string and remove comments

Reason

There are some old projects using emotion@10, and emotion10 runtime cannot handle comments correctly, emotion babel plugin can remove all comments in the css string so it is fine when using babel.

Benefits:

No need to use regex
Can strip comments like @emotion/babel-plugin

Questions:

I wrap the original css string in a selector to make parser works correct, not sure if swc_css has some API to parse css string like color: red instead of .sel { color: red }.

The should_not_trim_end_space_in_first_item test failed, it removes the last space, is this OK?
