…#24144)

These slice/`Vec`/`IndexVec`-backed accessors are already `ExactSizeIterator` internally (`slice::iter().map(..)` / `.copied()` / `.rev()`, `iter_enumerated()`, `HashMap::values()`, `(0..len).map(..)`) — the `impl Iterator` return type just erased it.

Widening to `impl ExactSizeIterator` lets callers pre-size collections from the known length:

```rust
let mut v = Vec::with_capacity(scoping.symbol_ids().len());
v.extend(scoping.symbol_ids().filter_map(..));
```

instead of growing a `Vec` through reallocs, and lets callers call `.len()` directly.

Backward-compatible: `ExactSizeIterator: Iterator`, so existing callers are unaffected.

Two ordering details make it compile:
- The `multi_index_vec!` `iter_ids` (`(0..len).map(..)`) is widened first so the bound propagates to `SymbolTable`/`ScopeTable`, which is what lets `symbol_ids`/`scope_descendants_from_root` widen.
- The delegating `TraverseCtx::ancestors` is widened after its `TraverseAncestry::ancestors` source — an opaque `impl Iterator` only re-exposes `ExactSizeIterator` if the inner signature declares it.

Widened accessors:
- **oxc_semantic**: `Scoping::{symbol_names, resolved_references, symbol_ids, scope_descendants_from_root, iter_bindings, iter_bindings_in}`, `AstNodes::{iter, iter_enumerated}`, `ClassTable::{iter_enumerated, iter_private_identifiers}`, `multi_index_vec!` `iter_ids`
- **oxc_traverse** / **oxc_minifier**: `TraverseAncestry::ancestors`, `TraverseCtx::ancestors`
- **oxc_formatter_core**: `SourceText::{bytes_from, bytes_to}`
- **oxc_codegen**: `Codegen::current_class_ids`

These accessors are already `ExactSizeIterator` internally — the `impl Iterator` return type just erased it. Widening to `impl ExactSizeIterator` lets callers pre-size collections from the known length (`Vec::with_capacity(iter.len())`) instead of growing through reallocs, and lets them call `.len()` directly. Backward-compatible: `ExactSizeIterator: Iterator`, so existing callers are unaffected.

| accessor | backing |
|---|---|
| `ChunkGraph::sorted_chunks` | `Vec<ChunkIdx>::iter().map(..)` |
| `PluginDriver::iter_plugin_with_context_by_order` | `&[PluginIdx]::iter().copied().map(..)` |
| `StmtInfos::iter_enumerated_without_namespace_stmt` | `IndexVec::iter_enumerated().skip(1)` (`Skip` preserves the exact len) |
| `HybridIndexVec::iter` | `Either<IndexVec::iter(), FxHashMap::values()>` (both arms `ExactSizeIterator`) |
| `ScanMode::iter` | `Either<iter::empty(), slice::iter()>` (both arms `ExactSizeIterator`) |
| `DependedRuntimeHelperMap::iter` | `[Vec<_>; N]::iter().enumerate().map(..)` |

The rest of the crate's `impl Iterator` accessors are correctly left alone — they use `filter_map` / `flat_map` / custom iterators that erase the length.

Same idea as oxc-project/oxc#24144.
