Support deviceOrientationAndMotionGrantType

It would be awesome to support deviceOrientationAndMotionGrantType as it is done with mediaCapturePermissionGrantType, otherwise every single time that you open/close the app the permit is required.

See: https://developer.apple.com/documentation/webkit/wkuidelegate/3795606-webview

If you don’t implement this method in your delegate, the system returns WKPermissionDecision.prompt.

This was already reported in the issue "Motion sensor permissions are asked repetitively": https://github.com/react-native-webview/react-native-webview/issues/2942

That issue was closed including a PR with a "solution" that was not merged: https://github.com/react-native-webview/react-native-webview/pull/2944

I can confirm that a patch for RNCWebViewImpl.m with the PR code works and the if we pass "grant", the popup is not shown.

I would like to know what was missing (there is some note of the author about using same prop mediaCapturePermissionGrantType) or something else?

Should be revive that and push forward?
