Options: Show error when updating all options exceeds max_input_vars.

Browse Source 
On sites with a large number of options, the number of inputs when saving all options via the /wp-admin/options.php page may exceed PHP's `max_input_vars` setting, this will prevent saving.

An error is now shown if this is the case.

Fixes #45438.
