memtx: fix tuple waste size calculation

The main part of the fix resides in the `small` submodule, see commit
"small: improve real_size calculation in small_alloc_info". Current
patch fixes the pointer that is passed to `small_alloc_info()` - it
should point to the `memtx_tuple` rather than `tuple`. Also `memtx_tuple`
contains `uint32_t version` that had not been accounted before, now these
4 bytes are added to the `header_size`.

Closes #10217

Title: Remove the note regarding `waste_size` from `tuple_object.info()`
Product: Tarantool
Root document: https://www.tarantool.io/en/doc/latest/reference/reference_lua/box_tuple/info/#box-tuple-info

Remove the following note: `waste_size` is provided for reference only and
can be inaccurate. Avoid using it for memory usage calculations.
