Use the original manufacturer and product strings for the joystick CRC

Browse source 
This allows the most information possible for the CRC string, which is used to differentiate controllers with the same VID/PID.

Fixes https://github.com/libsdl-org/SDL/issues/8724

(cherry picked from commit 1f1ee6f77c492e17a9691c367110c11529fab3fb)
