index: encapsulate virtual functions responsible for updates in memtx

Currently, the index methods virtual table has several functions that are
only used by the memtx indexes:
* `replace`;
* `begin_build`;
* `reserve`;
* `build_next`;
* `end_build`.

Let's introduce a separate `memtx_index_vtab` structure and encapsulate
these methods as a virtual table derived from `index_vtab`. This
encapsulation will further on allow us to augment the `replace` method with
additional context for supporting multikey indexes in memtx MVCC.

Closes #11722
Needed for #6385
