Subject: [PATCH] fix: added showSoftInputFocus handling for iOS new
 architecture (#45298)

Summary:
Fixes: https://github.com/facebook/react-native/issues/45297

In iOS New Architecture When we are passing `showSoftInputOnFocus` prop to TextInput as false it should prevent soft keyboard from showing.
Here, the problem is in Fabric counterpart of TextInput, there we are not handling `showSoftInputOnFocus` props anywhere.
