fix(node:vm): propagate async context tracking flag to NodeVMGlobalObject (#26542)

When a `SyntheticModule` callback was wrapped in an `AsyncContextFrame`
on the main globalObject (where async context tracking is enabled),
evaluating it on a `NodeVMGlobalObject` would crash because the tracking
flag wasn't propagated.

`AsyncContextFrame::call` checks `isAsyncContextTrackingEnabled()` to
decide whether to unwrap the frame — without the flag, it takes the fast
path and tries to call the `AsyncContextFrame` wrapper directly, which
is not callable.

The async context data (`m_asyncContextData`) was already shared between
parent and `NodeVMGlobalObject`, but the tracking flag was missing. This
adds propagation of `isAsyncContextTrackingEnabled` alongside the data.

**Repro:** `react-email` v5.2.5 preview server crashes when rendering a
template because it imports `node:async_hooks` (enabling async context
tracking) and uses `node:vm` `SyntheticModule` for module evaluation.

Fixes #26540
