Storage: Fix DataTypePtr is not shared as expected
* Introduce a class `DataTypePtrCache` and manage the shared cache of `DataTypePtr` instances.
* Introduce `DataTypeFactory::getOrSet(const ASTPtr & ast)` and try to find the cache with data type name as "ast->range.first, ast->range.second"
logging: Turn the logging level of "updateTableColumnInfo" into debug because that could cause lots of logging when restarting tiflash

Fix the issue that TiFlash may consume lots of memory when there are many `ENUM` columns on TiDB
