Comments: Include post permalink in comment reply link.

Include the post's permalink when generating reply links in `get_comment_reply_link()` to account for comments displayed on index and archive pages.

This reapplies [32786] which was inadvertently reverted in [42360].

Props justinahinon, donmhico.
See #33383.
Fixes #47174.
