Part of #27065
This PR touches functions used in templates. As templates are not static
typed, errors are harder to find, but I hope I catch it all. I think
some tests from other persons do not hurt.
I noticed that `issue_service.CreateComment` adds transaction operations
on `issues_model.CreateComment`, we can merge the two functions and we
can avoid calling each other's methods in the `services` layer.

To avoid deadlock problem, almost database related functions should be
have ctx as the first parameter.
This PR do a refactor for some of these functions.
Close #24195
Some of the changes are taken from my another fix
f07b0de997
in #20147 (although that PR was discarded ....)
The bug is:
1. The old code doesn't handle `removedfile` event correctly
2. The old code doesn't provide attachments for type=CommentTypeReview
This PR doesn't intend to refactor the "upload" code to a perfect state
(to avoid making the review difficult), so some legacy styles are kept.
