  [UIAsyncTextInput] Respect UIKit/async_text_input_(iphone|ipad) after rdar://119688719

Reviewed by Richard Robinson.

UIKit is splitting the `async_text_input` feature flag out into `async_text_input_iphone` and
`async_text_input_ipad` in rdar://119688719. To keep async text input enabled after this change, we
need to tweak our enablement logic to match these new names.

* Source/WebKit/Shared/ios/WebPreferencesDefaultValuesIOS.mm:
(WebKit::isAsyncTextInputFeatureFlagEnabled):

Pull this feature flag check out into a common helper method, and also continue checking against the
old `UIKit/async_text_input` name to make sure we don't inadvertently disable the feature on current
versions of UIKit in the build.
