it wasn't used for anything. no more `page.get().get().id`.
i did this simply to clean up the code (we haven't needed BTreePageInner
in probably at least 8 months or more?), but it also:
- makes practically every tpc-h query faster due to removing indirection
and refcell runtime borrowing every time the btree stack is accessed etc
- makes every SELECT * FROM users bench query faster
- drops the count() benchmark runtime by like half

The removed comment no longer matches the current code. The
OrderByRemapping struct and the surrounding comments are sufficient to
explain deduplication and remapping.
I added `IOContext` to `DatbaseStorage` IO trait and this struct will
carry the necessary ctx required for encryption (or checksums.). This
lets us set the encryption at outside and let the IO layer handle it
properly

This PR makes plenty of changes to the sync engine among which the main
ones are:
1. Now, we have only single database file which we use to directly
execute `pull` and `push` requests (so we don't have `draft` / `synced`
databases)
2. Last-write-win strategy were fixed a little bit - because before this
PR insert-insert conflict wasn't resolved automatically
3. Now sync engine can apply arbitrary `transform` function to the
logical changes
4. Sync-engine-aware checkpoint was implemented. Now, database created
by sync-engine has explicit `checkpoint()` method which under the hood
will use additional file to save frames needed for revert operation
during pull
5. Pull operation were separated into 2 phases internally: wait for
changes & apply changes
* The problem is that pull operation itself (e.g. apply) right now
require exclusive lock to the sync engine and if user wants to pull &
push independently this will be problematic (as pull will lock the db
and push will never succeed)
6. Added support for V1 pull protocol
7. Exposed simple `stats()` method which return amount of pending cdc
operations and current wal size

Go bindings have moved to their own repo
https://github.com/tursodatabase/turso-go
Otherwise it is a pain in the ass to have a Go module as a subdirectory
of another repository. and now, they can get the TLC that they needed,
as I found out that it never worked for windows, and the embedding
wasn't working properly in some cases. We want them to be plug and play.

There's no need to call io.now() unless debug tracing is on. Let's
micro-optimize commit_dirty_pages() to avoid the unnecessary call.

When we reverted the #2789 , we had already merged #2793 . That Pr used
some helper methods that were created in #2789. So I just added them
back here + fixed the simulator dockerfile.

We had missed #2794 because we don't get any visible feedback on PRs if
we return wrong results from TPC-H, so let's make that happen here.
