Options, Meta APIs: Prevent excessive notoptions key lookups.

When the notoptions key does not exist in a persistent object cache, it was requested hundreds of times until the first not-option is written.

This commit improves performance by setting the value to an empty array to prevent non-existent notoptions key from triggering multiple key lookups.

Follow-up to [4855], [14515].

Props tillkruess, dd32, spacedmonkey.
Fixes #56639.
