What problem does this PR solve?

Issue Number: close #22346

Problem Summary:

As mentioned in #22346, it is not intuitive to set the session variable before creating a table. What’s more, it is also inconvenient to change the variable back and forth in the case of mix usage.

What is changed and how it works?

What's Changed:

  • Update dependency: bump the parser to the latest version(which supports CLUSTERED and NONCLUSTERED keywords).
  • Apply new keywords: during creating a table, TiDB decides whether the primary key of a table is clustered according to the syntax, global variable tidb_enable_clustered_index and the config option alter-primary-key.
  • Add special comment: the TiDB-specific executable comment /*!T[clustered_index] xxx */ is added in the output from binlog and SHOW CREATE TABLE.
  • Others:
    • Change the available values of tidb_pk_type in information_schema.tables to {CLUSTERED, NON_CLUSTERED}.

Add && ctx.GetSessionVars().EnableClusteredIndex either to make it consistent with common handle?

A lot of tests will be broken. Let's do this in another PR when it is decided.

Shall we return a warning if model.PrimaryKeyTypeClustered && !ctx.GetSessionVars().EnableClusteredIndex?

No, the variable has lower priority.
