Media: Disable attachment pages for new installations. 

WordPress creates attachment pages by default for every attachment uploaded. On the vast majority of sites, these attachment pages don't contain any meaningful information. They do however exist, get indexed by search engines, and sometimes even rank in search results, leading to bad results for users and site owners.

This commit introduces a `wp_attachment_pages_enabled` database option to control the attachment pages behavior:

* On existing sites, the option is set to `1` on upgrade, so that attachment pages continue to work as is.
* For new sites, the option is set to to `0` by default, which means attachment pages are redirected to the attachment URL.
* Sites that want to enable or disable the attachment pages can set the option to `1` or `0`, respectively.

Follow-up to [2958], [3303], [7149], [34690].
