cocoa-cb: add support for macOS color space transformation (EDR/HDR)

by default utilises the color space of the screen on which the window is
located. if a specific value is defined, it will instead be utilised.

depending on the chosen color space the macOS EDR (HDR) support is
activated and that OS's transformation (tone mapping) is used.

Fixes #7341
