…e for PostgreSQL (#61433) ### What problem does this PR solve? Extend PostgreSQL CDC type support: - **New scalar types**: `macaddr8`, `xml`, `hstore` → mapped to Doris `STRING` in both `SchemaChangeHelper` (CDC DDL) and `JdbcPostgreSQLClient` (FE table creation) - **Array types**: `_*` prefix handling in `SchemaChangeHelper` → `ARRAY<T>` (e.g. `_int4` → `ARRAY<INT>`); expanded `supportedInnerType` in `JdbcPostgreSQLClient` with `numeric`/`json`/`jsonb`/`uuid` - **Array element conversion**: extracted `convertToArray()` in `DebeziumJsonDeserializer` to recursively convert each element through the same type-aware logic as scalar columns, fixing timestamp array elements being stored as raw epoch microseconds
