MDEV-15380 Index for versioned table gets corrupt after partitioning and DELETE
In a test case Update occurs between Search and Delete/Update. This corrupts rowid
which Search saves for Delete/Update. Patch prevents this by using of
HA_EXTRA_REMEMBER_POS and HA_EXTRA_RESTORE_POS in a partition code.
This situation possibly occurs only with system versioning table and partition.
MyISAM and Aria engines are affected.

Closes #705
