Try to find OpenEXR 3 first via the upstream cmake config and fallback to using our FindOpenEXR

The formula was found in Qt's qt_pixelMultiplier (qpagesize.cpp)
as called by the deprecated setPaperSize method (when the unit is
DevicePixel)

GIT_SILENT

Should help produce better diffs and clang-format won't squash the enum
on one line.

GIT_SILENT

The HDR QImageIOHandler plugin only supports the default image orientation (-Y +X) in .hdr files. It mixes up the width and height however, resulting in non-square images not loading.

This fix adds a check for the standard image orientation in the file and returns false (with error message) if that fails.
If it succeeds, it takes the height from the -Y component, and the width from the +X component, resulting in successful loading of the image.

Add autotest images for landscape and portrait HDR (Radiance RGBE) loader

BUGS: 433877

Due to various double vs float arithmetic,
some primaries could be rejected by Qt.
If necessary, we adjust the values so they
will be accepted by Qt.

Remove newline from the ends of error strings.
