Stop using deprecated remove_prefix to clear era information in Staking Pallet #13439
Description
We currently clear state for eras older than HistoryDepth by using the fn map.remove_prefix which is deprecated. Use map.clear_prefix that can be paged.
This is how we clear old era information today
/// Clear all era information for given era.
pub(crate) fn clear_era_information(era_index: EraIndex) {
#[allow(deprecated)]
<ErasStakers<T>>::remove_prefix(era_index, None);
#[allow(deprecated)]
