 Rewrite Rules: Prevent stampedes when flush_rewrite_rules() is called

 This ensures that the `rewrite_rules` option is not emptied until the new
 value has been recalculated and the option is updated. The logic for
 refreshing the option value is moved to a new private method named
 `WP_Rewrite::refresh_rewrite_rules` which is used by both the
 `flush_rules` and `refresh_rewrite_rules` methods.

 Props iCaleb, joemcgill, flixos90, mukesh27.
 Fixes #58998.
