hdr Dolphin Emulator adds HDR Enhancement Shaders

[Sampajama]

In case you haven't seen, Dolphin just added support for HDR Enhancement shaders and included some in the emulator. I'm the developer of the PerceptualHDR shader, and I tuned it to work especially well on Nintendo Games.

A lot of math wen't into making this shader look correct on an HDR screen. For my testing I had the pleasure of testing on the MBP16 XDR screen, which can go up to a blinding 1600 nits. I don't have access to RTX HDR, but I like to believe it's somewhat comparable (even if it's just tone mapping instead of AI). But I'd really like to get your guy's opinions on the addition. 

You can read more about it here:

I'll attach some of the example images below. Goes without saying, you can only see the difference on an HDR screen.
