fix(glob): css imports injecting a ?used query to export the css string

[poyoho]

Description

fix: #6938

Additional context

import 'xx.css' had inconsistency.

in importAnalysisBuild plugins differentiate CSS imports, and add used query in the css import expression. glob / globEager feature also not default import but get emtry string.
this PR add the ?used in the glob / globEager import

Differentiate CSS imports that use the default export from those that
do not by injecting a ?used query - this allows us to avoid including
the CSS string when unnecessary (esbuild has trouble tree-shaking
them)

I think the code is going to be more clear if we change it to

} else {
  const importeeUrl = isCSSRequest(importee) ? `${importee}?used` : importee
  if (isEager) {
    ...
  }
  else {
    ...
  }
}

We can avoid repeating the condition, and the main else makes it more evident that we are dealing with the non-raw case in both branches.

I seem to have found a pattern that when a fragment is reused it should be extracted. 😀

[patak-cat]

ha, not always, early abstraction is sometimes worse than duplicating code. But in this case, the variable applied to both branches when it was non-raw. I moved inside the else case, as it is not used in the raw branch.

thanks @patak-dev this is good change.

[poyoho]

oh, It was already suggested, but I didn't notice it. Thanks for showing me the good case.
