1. Feature: Retrieve Key Log IDs via RaftLogReader::get_key_log_ids() …

   Key log IDs represent the first log IDs proposed by each Leader. These
   IDs enable Openraft to efficiently access log IDs at each index with
   a succinct storage.
   
   Previously, key log IDs were obtained using a binary-search-like
   algorithm through `RaftLogReader`. This commit introduces the
   `RaftLogReader::get_key_log_ids()` method, allowing implementations to
   directly return a list of key log IDs if the `RaftLogStorage` can
   provide them.
   
   For backward compatibility, a default implementation using the original
   binary-search method is provided. No application changes are required
   when upgrading to this version.
   
   Tests verifying the implementation are included in
   `openraft::testing::log::suite::Suite`.
   
   - Fixes: databendlabs#1261
