Networks and Sites: Revert the use of the metadata API for `*_network_options` functions. 

[54080] refactored the logic in `get_network_option()`, `update_network_option()` and `delete_network_option()` to use the metadata API. However, this change resulted in issues with large multisite installs that utilize memcached having network options > 1MB in size.

This change reverts [54080] and all related follow-up changes.

Reverts [54080], [54081], and [54082].  Partially reverts [54267] and [54402].

Props pavelschoffer, rebasaurus, johnbillion, spacedmonkey, desrosj, rinatkhaziev.
Fixes #56845.
See #37181.
