Android: loading indicator shows while buffering and cannot be disabled

**Describe the bug**
On Android, a loading spinner is shown in the center of the player while buffering. It is drawn by the SDK's `PlayerView` and there is no way to turn it off — `controlsEnabled = false` only affects `PlayerControlView`. iOS does not show anything, so the two platforms behave differently. Apps that render their own loading UI end up with two indicators on top of each other.

**To reproduce**
1. Render `` on Android.
2. Watch the center of the player while it buffers (initial load, or a rebuffer during playback).

**Expected behavior**
Either no built-in indicator, or a prop to opt out so it matches iOS. e.g.

```tsx

```

**Additional context**
React Native 0.81. Android only.

Start at the IVSPlayer entry point and follow how Android's PlayerView draws the buffering indicator, especially the existing controlsEnabled behavior. Add an opt-out matching the proposed hideLoadingIndicator prop, then verify that buffering shows no built-in spinner when disabled and that the normal indicator remains available otherwise.
