Detailed description

As originally reported in #17532 there is a frequently occurring problem when trying to use the -[Mat toUIImage] method and other similar methods.
The "unrecognized selector sent to instance" error can be worked round by modifying the "Other Linker Flags" but its a pain to always have to do this. Other functionality like debug Quicklook (#20457) also requires these flags to be set in order to work correctly and there is no hint in the UI to indicate that this is the case.
To solve the problem we need to move the functionality added to Mat using categories in Mat+Converters and Mat+Quicklook directly into the Mat implemenation

Steps to reproduce

Refer to #17532
