[fix](be) Own values in single-value aggregate states

[Mryange]

Single-value aggregate state implementations were duplicated across aggregate functions, and complex values were not handled consistently. In particular, window functions such as first_value, last_value, nth_value, lead, and lag retained a raw input column pointer and row offset. The input column can be cleared while the window state is still alive, leaving the state with an invalid reference.

Root cause: the shared state abstraction did not own complex values, so aggregate functions either maintained separate implementations or referenced input columns directly.

This change introduces reusable fixed-width, string, and owned-column single-value states. The column-backed state materializes exactly one selected row and is reused by complex min, max, min_by, max_by, and window value functions. Unsupported complex comparison types use non-incremental window evaluation. Existing fixed-width and string state serialization formats are preserved.

Tests cover value ownership after source-column reclamation, comparison and serialization, and verify that retained column allocation does not scale with the number of source rows.
