Description
Currently, we can only compare the row count between TiFlash and TiKV, which is far from enough. Consider extending the capability of ADMIN CHECK TABLE or ADMIN CHECKSUM TABLE.

Research direction
Start by tracing the existing row-count comparison behind ADMIN CHECK TABLE and ADMIN CHECKSUM TABLE, then inspect how TiFlash and TiKV expose field values for comparison. Define the consistency scope and validation behavior before implementing; done means the selected command can detect mismatched field contents, not only row counts, with coverage for the relevant cases.
