fix(ssr): apply alias to resolvable dependencies during dev

[hi-ogawa]

Description

• closes ssrLoadModule fails to respect preact/compat aliases, while the SSR bundle does respect preact/compat aliases #15503

I found this dev/build inconsistency while investigating the issue #15503 (comment), but the issue itself seems to be more complicated and currently it's waiting for proper reproduction. (EDIT: I think this is the only vite side issue, so we can close it if this PR is merged.)

Given that there is a big warning in https://vitejs.dev/guide/ssr.html#ssr-externals, I suppose relying on resolve.alias might not be recommended in general. However, considering this is one source of dev/build inconsistency for non-external modules, so I thought this is worth making it consistent. Please let me know if this fix is appropriate here.

Previous behavior was that:

  {
    dep: 'original',
    nonDep: 'ok',
    builtin: undefined,
  }

which is inconsistent with build mode.
