fix: addresses comment https://github.com/tursodatabase/limbo/pull/897#discussion_r1948154297 by @pereman2
...
this commit adds the final touches to the state machine for btree_destroy and also introduces a state machine for clear_overflow_pages
this addresses the issue of IO interrupting an operation in progress and solves the following problems:
* performance issues with repeating an operation
* missing page issues with clear overflow pages

Merge 'Remove unnecessary reference counting from completion I/O callbacks' from Preston Thorpe
...
I am on a bit of a mission to revisit a lot of the ref counting, this

It seems to be a linear path of function calls or hashmaps which can own
the completions directly, no cloning needed.
