Add more `requires` to tests for easier dialect tests management

Add more `requires` to tests for easier dialect tests management

<!-- Provide a general summary of your proposed changes in the Title field above -->

### Description
<!-- Describe your changes in detail -->
I am just going through starrocks dialect tests. I have figured out that adding some requires for tests may be useful also for other dialects. So this is a proposal of adding them to sqlalchemy. Please let me know if it is aligned with your approach.

### Checklist
<!-- go over following points. check them with an `x` if they do apply, (they turn into clickable checkboxes once the PR is submitted, so no need to do everything at once)
