AutoHDR now uses queried or user settings for HDR

Browse Source 
If the user hasn't set a HDR DISPLAY MAX NITS, the first time a game is launched using DirectX11 or 12, the queried display values are saved in the ini

Of course user settings always take preference.

But for someone that doesn't have the HDR settings set, the correct default value should be set so clipping and those bright neon/fluorescent colors can be avoided.
