fix: Chinese or other nonalphabetic language maxLength bug on iOS

[aoarashi1988]

Summary

When input Chinese or Japanese even other nonalphabetic language word , the calculation of text length is wrong, you use the alphabet in TextInput instead of the real word they want to input。
It's an old issue, but still remain in the up-to-date version of react-native, just like the issue #18990.

Changelog

Take markedTextRange into consideration.

Does this issue repro with multi character length emojis as well? If so, can you provide a small repro code?

Having a repro case for this that works when the device language is english would be super helpful as we can put it in the RNTester test suite and make sure it doesn't break in the future.
