This image is suitable for release, debug and debug-asan builds.
The image is somewhat heavy (1.08 GiB) due to llvm-18, but don't run
tarantool's CI that often.

This causes warnings if compiled with clang-18. Let's define a sane
upper limit for the max tree depth and use it for allocating arrays
on stack. Note that we don't really care about performance because
sptree is used only in unit tests.

Closes #10354

Apparently, clang 18 is not particularly happy about luajit's static
assert implementation:

Picodata SQL now manages the Tarantool statement cache using a
dedicated SQL fiber that handles preparation and unpreparation of
statements based on an LRU eviction policy. Prepared statements
can be executed across different sessions by SQL clients.

Previously, when a client executed a prepared statement, it
increased the reference count in the statement cache and linked
the statement to the client's session. While this approach seemed
fine, it caused issues during eviction, as references to these
statements remained in client sessions, preventing proper eviction.

This commit addresses the issue by ensuring that if a statement is
added to the current session during execution, it is removed and
the session state is restored once execution is complete.

Temporary spaces, used for cluster-wide SQL data materialization,
were causing unnecessary netbox schema version bumps, leading to
schema downloading via netbox, excessive Lua garbage and GC blocks.
Since these tables are for internal SQL use, we don't need to inform
netbox clients about schema changes. We now maintain separate schema
versions: one for netbox clients and one for the internal prepared
statement cache.

- If you prepare and execute statement with params
in the projection and then unprepare the
statement, byte counter may show the wrong value
or even overflow.
- The problem is that when we compile sql
statement, we set parameter type to 'any'.
But when we execute the statement we set parameter
type to actual type. Then we use this type in
calculation of estimated of sql cache entry size.
This leads to different estimated sizes of cache
entry during prepare and during unprepare after
statement was executed
- Fix this by resetting type to 'any' after
executing the statement

BREAKING CHANGE!:
1. add session id argument to sql_prepare_ext
2. introduce sql_unprepare_ext function.
This function removes prepared stmt using
given session id.

In picodata SQL, we may prepare stmt in one
session and unprepare it in some
other session, which does not know in
what session the statement was prepared. Now
sql_prepare_ext returns not only statement id,
but also a session id. This way statement can
be unprepared from other session using
sql_unprepare_ext.

WAL extensions allows to add auxiliary information to each
write-ahead log record. WAL extensions configured by
`box.cfg.wal_ext` option. Currently, there is only one builtin
extension: `new_old`. `new_old` extension add information about

BREAKING CHANGE!:
1. remove sql_prepare from the export list;
2. introduce sql_prepare_ext.

The sql_prepare symbol previously included the tarantool port as
an output parameter. However, this structure was inconvenient for
libraries using the C API, as they primarily required just the
statement ID. To address this issue, the sql_prepare symbol was
replaced with the sql_prepare_ext symbol.

Previously, users with multiple connections to tarantool instance
couldn't share prepared statements across sessions. They had to
manually call prepare in each session before execution.

This commit automates this process for the exported version of
SQL prepared statement execution (sql_execute_prepared_ext symbol).
Original Lua execution keeps the old behavior for backward
compatibility.

Previously, sql_prepare_and_execute and sql_execute_prepared

BREAKING CHANGE!:
1. sql_bind_list_decode - removed
2. sql_execute_prepared_ext - new arguments
3. sql_prepare_and_execute_ext - exported

There were several reasons to refactor the API.
1. sql_bind_list_decode (decodes message pack parameters into
   internal C bind structure) is very difficult to use without
   memory leaks (as it allocates results on fiber()->gc).
2. sql_execute_prepared_ext missed vdbe step limit in parameters
   and used the default value.
3. Sometimes SQL queries don't fit into prepared statement cache
   and the user still wants to execute them via a slow pass with
   full compilations from the query text. That was the reason to
   export sql_prepare_and_execute_ext symbol.

The following commit introduced a tautological if expression:

```gitcommit
sql: introduce structs assembling DDL arguments during parsing (ba56b145fafaa3)
```

Due to the changes in commit

```gitcommit
sql: refactor memory allocation system (cb777136dd7a0c)
```

the allocations in sql expressions became infallible, which means
that we may safely fix static analysis warnings by dropping the
tautological comparison altogether.
