parser : support admin repair table syntax

[AilinKid]

What problem does this PR solve?

For ISSUE to fix tableInfo (Meta) in KV store.
Bad tableInfo will be loaded error leading TiDB crash when it restart.
So we support a new syntax to repair bad tableInfo in meta (using new tableInfo build from create table statement to override the bad tableInfo, that means user should keep new tableInfo correct)

Backgound : In some corner cases or encountering serious bugs, DDL operations update table structure error occurred, causing TiDB panic and failing to restart the service.

ADMIN REPAIR TABLE  table_name CREATE TABLE STATEMENT

The syntax looks weird. What happens with ADMIN REPAIR TABLE x CREATE TABLE y ... ?

just rename the table, cause override will use the old table id, index id, so it's ok.
