[Feature] [BanyanDB] Support some incompatible schema upgrade through versionized group mechanism

[wu-sheng]

Considering #12442, let's add a database version number concept in OAP codebase. Once we have this in place, we have a chance to do incompatible upgrade through two group.

e.g. banyandb_db_schema_v = 1, and we need some incompatible upgrade, introduced a new kind of index, but the query logic is consistent. We could do banyandb_db_schema_v=2(compatible with banyandb_db_schema_v=1).

Then, when we apply definition change through create new schema_v suffix groups.
