tablemode need RefreshMeta interface to reload tidb schema diff when BR log restore occur exchange partition

[River2000i]

Enhancement

When BR uses Tablemode, which is expected to be set to RestoreMode when full restore batch crate tables, including tables created during log backup. However, if an exchange partition occurs during log backup, the table will still be a partition during full restore. In log restoring, the table ID will exchange with partition ID, which exchange by meta kv directly instead of infoschema, so the table mode cannot be modified for the table(since the new table ID is not store in infoschema).
