Fix: Two-finger scroll issue when TalkBack is active

[mika-lindell]

My best effort on fixing #336

• Does it by disabling onTouchEvent for all wheels but the one having accessibility focus (IosClone)
• Shouldn't affect anything when TalkBack isn't active

Thanks, looks great! What about the nativeAndroid variant, does it already work as intended or does it need a fix too?

[mika-lindell]

nativeAndroid variant seems to work for the two finger scrolling part. I noticed it has some issues when reading focused element out loud. For example when values change. Also it might be missing some accessibility labels which would explain context a bit. Some of it could be because our project as well.

Would prefer to have as much of the accessibility-related code in the accessibility class, so I moved it around a bit. Could you confirm it still works as intended? 🙂

[mika-lindell]

That looks much better! I might be making some more accessibility-related PRs, so I'll try to follow that example.

Also, the 2-finger TalkBack scroll seems to work as expected.

Thanks, that's appreciated! Release this fix in v3.4.3
