Wire FFI_TableProvider / TableProvider(ABC) through to the Rust TableProvider trait

Split out from #1577 (item 2).

Unlike `CatalogProvider` / `SchemaProvider`, wiring a plain-Python `TableProvider` subclass through to the Rust `TableProvider` trait needs a new `RustWrappedPyTableProvider`, analogous to `RustWrappedPySchemaProvider` in `catalog.rs`. It has to cover `scan()` returning an `ExecutionPlan`, `supports_filters_pushdown`, and statistics.

This is execution-engine work, not a typing-only change, so it doesn't belong in a typing PR. Opening as its own issue so the design (partial pushdown support, how statistics get surfaced to the Python side) can be discussed before someone picks it up.

首先閱讀 catalog.rs，尤其是 RustWrappedPySchemaProvider，並查看 #1577 中的第 2 項。追蹤 TableProvider(ABC) 和 Rust TableProvider 的入口點，然後釐清 scan()、supports_filters_pushdown 和 statistics 應如何跨越邊界。完成的標準是 wrapper 及其 partial-pushdown 和 statistics 行為已實作並達成共識。
