Subject: [PATCH] fix: do not overwrite external `inputAccessoryView` on Fabric
 (#48339)

Summary:
If 3rd party libs are using `inputAccessoryView` - the current code can easily break it. Whenever props gets changed we call `setDefaultInputAccessoryView` which will simply overwrite the current `inputAccessoryView` (which is highly undesirable).

The same fix on paper was made ~7 years ago: https://github.com/facebook/react-native/commit/bf3698323d81508fc77174df2b1ffe5fb03224e7
