Adapt to the new fields of tiflash system table #62295
Description
Enhancement
TiFlash issue: pingcap/tiflash#10272
TiFlash PR: pingcap/tiflash#10275
In order to improve the observability for TiFlash OOM risk under wide-column scenario, tiflash added delta_cache_alloc_size to system.dt_segments and column_count,delta_cache_alloc_size to system.dt_tables.
For the tidb side, it should add related columns to the information_schema.tiflash_tables and information_schema.tiflash_segments for retrieving the result from tiflash instances.
