This PR do some performance optimzations. - [x] Add `index` for the column `comment_id` of `Attachment` table to accelerate query from the database. - [x] Remove unnecessary database queries when viewing issues. Before some conditions which id = 0 will be sent to the database - [x] Remove duplicated load posters - [x] Batch loading attachements, isread of comments on viewing issue --------- Co-authored-by: Zettat123 <zettat123@gmail.com> Conflicts: models/issues/comment_code.go: function was renamed in Forgejo models/migrations/migrations.go: migration already ported
