Add EXR support for screenshots

Add various functions to use FLinearColor in addition to FColor
Add support for EXR on platforms supporting HDR, but not openexr. This is driven by WITH_UNREALEXR_MINIMAL: the screenshot will not be compressed, only writes are supported, only RGBA float32 is supported as input (FLinearColor), and output will be RGB float16.
The convention used is ScRGB, not BT2100-PQ to store the HDR data, since the viewers I tested with were expecting ScRGB .

tested (both png and exr):
Editor d3d11/d3d12: F9 / highresshot 2 / High Resolution Screenshot Tool w/ and w/o Custom Depth Mask, w/ and w/o Buffer attributes / Trace.Screenshot
Game: shot / shot -showui / highresshot 2 / BugScreenShot / BugScreenShotWithHUDInfo (but HandleBugScreenShot is empty) / Trace.Screenshot / Trace.Screenshot w/ ui

What doesn't work : ScreenshotCapturedDelegate.Broadcast in HDR
