BigQuery allows a query to start with `FROM`, e.g. `FROM t` and `FROM t SELECT *`, which is also the entry form for pipe syntax (`FROM t |> ...`). The parser already supports FROM-first `SELECT` behind `Dialect::supports_from_first_select()` (enabled for ClickHouse, DuckDB and Generic); this enables it for BigQuery as well. The existing `test_select_from_first` / `test_select_from_first_with_cte`, parameterized over `all_dialects_where(|d| d.supports_from_first_select())`, now cover BigQuery.
