[fabric] Copy accessibility attributes when switching TextInput backing view

Summary: This diff adds the copy of the a11y attributes when switching the TextInput to the secure text entry which triggers the switch to a NSSecureTextField and runs the copy of the NSTextField attributes to the new backing text field.

Test Plan:
- Run Zeratul with Fabric enabled and inspect the Messenger password field on the auth screen using the Accessability Inspector to check that the attributes are passed down to the native text field.
