[7.x][ML] Handle data frame analytics state spreading over multiple docs (#62564) (#62824)
When state persistence was first implemented for data frame analytics
we had the assumption that state would always fit in a single document.
However this is not the case any more.

This commit adds handling of state that spreads over multiple documents.

Backport of #62564
