Changelog for Runtime Dev

[#7365]: Use checked math in frame-balances named_reserve
This PR modifies named_reserve() in frame-balances to use checked math instead of defensive saturating math.
The use of saturating math relies on the assumption that the value will always fit in u128::MAX. However, there is nothing preventing the implementing pallet from passing a larger value which overflows. This can happen if the implementing pallet does not validate user input and instead relies on named_reserve() to return an error (this saves an additional read)
This is not a security concern, as the method will subsequently return an error thanks to <Self as ReservableCurrency<_>>::reserve(who, value)?;. However, the defensive_saturating_add will panic in --all-features, creating false positive crashes in fuzzing operations.
[#7460]: Update SCALE codec indices
We need this in order to be able to update parity-scale-codec to the latest version after it's released. That's because parity-scale-codec added support for checking for duplicate indexes at compile time.
[#7437]: Remove dead code
Remove unused code
