Remove duplicated category NSTextStorage+FontScaling (#41437)

Summary:
We have two same categories of `NSTextStorage+FontScaling`, another one is  https://github.com/facebook/react-native/blob/main/packages/react-native/Libraries/Text/Text/NSTextStorage%2BFontScaling.h. Only one category is valid, so we can delete one.

## Changelog:
