fix: scrollRectToVisible on frame size change in RCTTextInputComponentView

[abulenok]

Summary:

Fixes #58517

UIKit checks caret visibility inside the text change, but RCTTextInputComponentView
grows RCTUITextView one mount later (the new size comes from Yoga). The new line has no layout yet, so the check reveals the old line, and UIKit never checks again.

Fix: when updateLayoutMetrics applies a taller frame to a focused input do scrollRectToVisible - growth and scroll land in the same mount

Changelog:

[IOS] [FIXED] - Fixed multiline TextInput inside a ScrollView not being scrolled when a new line is entered on the New Architecture
