Reduce memory usage in component fetches and change detection filters

[ItsDoot]

Objective

• Adopted Make the pointers in Fetch and Query's iterators unions #6396

Solution

Same as #6396, we use a compile-time checked StorageSwitch union type to select the fetch data based on the component's storage type, saving >= 8 bytes per component fetch in a given query.

Note: We forego the Query iteration change as it exists in a slightly different form now on main.

Testing

• All current tests pass locally.
