feat: remove UIGraphicsBeginImageContextWithOptions from repo (#2117)

Browse Source 
Since UIGraphicsBeginImageContextWithOptions will be depracated in iOS 17 (developer.apple.com/documentation/uikit/1623912-uigraphicsbeginimagecontextwitho), I changed the implementation to not use it and use UIGraphicsImageRenderer instead.

Also added Mask examples to be able to test it.
