[ML] Add test to prove categorization state written after lookback (#55297)
When a datafeed transitions from lookback to real-time we request
that state is persisted from the autodetect process in the
background.

This PR adds a test to prove that for a categorization job the
state that is persisted includes the categorization state.
Without the fix from elastic/ml-cpp#1137 this test fails.  After
that C++ fix is merged this test should pass.

Backport of #55243
