fix(ios): selection range not respected when changing text or selection when selection is forced (#50166)

Summary:
fix: #50132
The goal of this PR is to ensure selected TextInput scrolls to the selected range when text or selection change.
The background of this feature check is to implement a rich text editor.

## Changelog:

[IOS][FIXED] - Selection range not respected when changing text or selection when selection is forced

Pull Request resolved: #50166

Test Plan:
Tested with the sample linked to this pull request.
As TextInput is a controlled component

Here is a video of the sample with the patch: https://drive.google.com/file/d/1lS9_70quNqND_E8MjLFcRG6HoHcDkfmv/view?usp=drive_link

First TextInput shows the initial issue reported in the ticket.
Second TextInput shows the global behavior of the controlled component, the 2 buttons allows to force focus and the force text values

I have also backport this part on 0.77.1 and test it in my app, it works fine for me (let's see if I have QA feedback)
