[ios][pv] accept/reject gesture based on hitTest (with new widget API) (#179659)
This is a follow up PR to [this original
PR](https://github.com/flutter/flutter/pull/177859).

The difference is the API - the original PR chooses Option 1 [in the
design
doc](https://docs.google.com/document/d/1ag4drAdJsR7y-rQZkqJWc6tOQ4qCbflQSGyoxsSC6MM/edit?tab=t.0),
while this PR chooses Option 3.

## Usage

To directly use flutter API, just pass in the policy when creating
UiKitView widget.

```
UiKitView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy)
  ...
)
```

For plugins, we need to update plugins to use this new API. 

```
WebView(
  ...
  gestureBlockingPolicy: UiKitViewGestureBlockingPolicy
) {
  return UiKitView(
    ..
    gestureBlockingPolicy: gestureBlockingPolicy
  )
}
```

PR](https://github.com/flutter/flutter/pull/177859).
