What problem does this PR solve?

Issue Number: close #5154

Problem Summary:

What is changed and how it works?

in decodingSchemaSnapshot, we use column name instead of offset to find cluster index id of the common handle. Because in tiflash, we don't update the indexinfo of table_info except rename ddl action. Thus, the offset of tidb_table_info is not correctly in sometimes.

Besides, I add two DDL tests based on issue #5154, concerning about clustered index.

Check List

Tests

  • Unit test
  • Integration test
  • Manual test (add detailed scripts or steps below)
  • No code

Side effects

  • Performance regression: Consumes more CPU
  • Performance regression: Consumes more Memory
  • Breaking backward compatibility

Documentation

  • Affects user behaviors
  • Contains syntax changes
  • Contains variable changes
  • Contains experimental features
  • Changes MySQL compatibility

Release note

Fix the TiFlash crash issue that occurs after dropping a column of a table with clustered indexes under some situations.

maybe also add a check in RegionBlockReader::readImpl before returning true to ensure all the columns in the decode block have the same row number?
