Map TextInput textContentType strings to Objective-C constants (#22611)

Summary:
This is an updated version of #22579 which uses compile conditionals to prevent `use of undeclared identifier` errors when compiling on older versions of Xcode.

--------

Currently the only `textContentType` values that work are: `username`, `password`, `location`, `name` and `nickname`. This is due to the strings provided by React Native not matching up with the underlying string constants used in iOS (with the exception of the aforementioned types). Issue #22578 has more detail examples/explanation.
Pull Request resolved: #22611
