Do some performance optimize for issues list and view issue/pull (#29515)

Browse Source 
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
