John McCutchan af107ceba5 Add an AndroidManifest.xml flag to disable ImageReader backed Platform Views (flutter/engine#46430)
An internal customer is seeing flickering on some high FPS phones.

While we try and reproduce / gain more knowledge of this problem this PR adds a AndroidManifest.xml flag to disable their usage.

The boolean flag is:
```
"io.flutter.embedding.android.DisableImageReaderPlatformViews"
```

Adding the following to your manifest will disable their usage:

```
<meta-data
  android:name="io.flutter.embedding.android.DisableImageReaderPlatformViews"
  android:value="true" />
```
