Gang Liao d7ebb58cb5 Add blob cache tickers, perf context statistics, and DB properties (#10203) 
Summary:
In order to be able to monitor the performance of the new blob cache, we made the follow changes:
- Add blob cache hit/miss/insertion tickers (see https://github.com/facebook/rocksdb/wiki/Statistics)
- Extend the perf context similarly (see https://github.com/facebook/rocksdb/wiki/Perf-Context-and-IO-Stats-Context)
- Implement new DB properties (see e.g. https://github.com/facebook/rocksdb/blob/main/include/rocksdb/db.h#L1042-L1051) that expose the capacity and current usage of the blob cache.
