Toggle secureTextEntry cursor spacing (#23524)

Browse Source 
Summary:
This is a fix for #5859, based on the feedback in #18587. Instead of using `didSetProps` it uses a setter. I will also note that setting to `nil` no longer works (crashes) so setting it to a blank string then back to the original works fine.

[iOS] [Fixed] - Toggling secureTextEntry correctly places cursor.
