Networks and sites: use get_allowed_mime_types to populate multisite’s upload_filetypes.

Ensure new multisite installs are up to date with the current mime types supported in core.

Note that this will only affect newly created networks, since this is only used to populate the schema for new networks, not change the allowed mime types for existing networks

Props spacedmonkey, costdev, pavanpatil1, joemcgill, rajinsharwar, tb1909.
Fixes #53167.
