This PR replaces the Get*CallbackAtIndex pattern in the PluginManager with returning a snapshot of callbacks that the caller can iterate over using a range-based for loop. This is a continuation of #184452 which added thread safety by using snapshots. However, that introduced a bunch of unnecessary copies which are largely eliminated again by getting the snapshot once when gather all the callbacks, rather than doing that on each iteration when querying a plugin for a given index. It also eliminates the possibility of the snapshot changing underneath you when iterating over the plugins. This change was largely mechanical and I used Claude to do the menial work of updating the signatures and call sites.
