fix infinite updates from KeyboardAvoidingView

[Kudo]

Summary:

Fixes #45192. In the issue, it has two different issues and coming from different root cause actually:

1. in the repro 1, it is because android onLayout/keyboardDidShow convert size between pixel and dp. it comes with round-off error. the non-integer number does not fall into the return statement and goes into infinite setState -> onLayout calls.
2. in the repro 2, it is because the keyboardVerticalOffset props. when keyboardDidHide, the keyboardY should not count for keyboardVerticalOffset.
