Support detach on transaction prepare

Browse Source 
Split method `transaction::xa_detach()` in `before_xa_detach()` and
`after_xa_detach()`. This allows to handle bf abort or replay while
transaction is detaching and to distinguish if a transaction is bf
aborted before or after the DBMS has detached a transaction from its
storage engine.
