We currently return the exact same error from two different IdxDelete
paths. Improve the messages with context about what we're doing to make
this error more debuggable.
I've added a trait called `CursorTrait`. I know it's not a good name for
now, but I didn't know what tto change then enum `Cursor` to. This trait
wraps all common functionality, and some functionality that is yet too
specific that needs to be fixed.
This is needed in order to have layered cursors where for example,
MvccCursor will need a fallback BTreeCursor.

Prevents something like `WHERE x = 5 AND x = 5` from becoming a two
component index key.

This PR introduces sparse vectors support and jaccard distance
implementation.
Also, this PR restructure the code to have all vector operations in
separate files (they grow pretty quickly as new vector representations
added to the DB).
Closes#3647
Various little fixes to `Sorter` that reduce unnecessary work.
Makes TPC-H query 1 roughly 2x faster, which is a lot because it
originally took 30-40 seconds depending on the CI run

I found an application in the open that expects sqlite_version() to
return a specific string (higher than 3.8...).
We had tons of those issues at Scylla, and the lesson was that you tell
your kids not to lie, but when life hits, well... you lie.
We'll add a new function, turso_version, that tells the truth.

- On each interaction we assume that the value is NULL, so we need to
set it like so for every interaction in the list. So we force to not
emit this NULL as constant;
- Forces a copy so IN expressions works inside an aggregation
expression. Not ideal but it works, we should work more on the query
planner for sure.

- errors are hard to handle in case of some scan operations (something went wrong in the middle - whoe query aborted)
- it will be more flexibly if we will return NaN and let user handle situation
