vo_gpu: allow higher icc-contrast and improve logging

Browse Source 
With the advent of actual HDR devices, my real measured ICC profile has
an "infinite" contrast, since the display is completely off on pure

1m:1 to be safe.

Also, improve the logging in the case that the detected contrast is too
high by default.

Specifies an upper limit on the target device's contrast ratio. This is
detected automatically from the profile if possible, but for some profiles
it might be missing, causing the contrast to be assumed as infinite. As a
