Review Comment:
A single connection can only handle a single query at a time anyways.
Though, exposing the name may be useful if we want to somehow expose managing
multiple prepared statements on a single connection. (I suppose that could be
one way to allow multiple AdbcStatement instances from a single AdbcConnection,
with the restriction that you can't use them concurrently, and that one result
set must be completely consumed before using a different statement.)
