Rename RCTUIGraphicsImageRenderer to `RCTMakeUIGraphicsImageRendere…

…r` (#46772)

Summary:
Because `UIGraphicsImageRenderer` doesn't exist on macOS, I need to shim it for React Native macOS (See microsoft#2209). I planned to use the name `RCTUIGraphicsImageRenderer`. However.. it seems that is used by a static helper function in `RCTBorderDrawing.m`. So.. let's rename it? The function is just a helper method to make an instance of the class, so I think the name `RCTMakeUIGraphicsImageRenderer` is slightly more idiomatic anyway.

This method is not public, so it should not break the public API of React Native.

## Changelog:

[IOS] [CHANGED] - Rename `RCTUIGraphicsImageRenderer` to `RCTMakeUIGraphicsImageRenderer`

Pull Request resolved: #46772

Test Plan: CI should pass
