458054 Fix JPEG-XL HDR support

Amy spark requested to merge lsegovia/krita:work/amyspark/jxl-hdr-chromium into master

The version of libjxl we were using had broken support for linear HDR, and updating it revealed some last-minute ABI breaks upstream.

To fix it, I'm updating libjxl to the 0.7 RC and highway to latest main.

I've also fixed an import error, where I didn't account for 16-bit float nor if the requisite OpenEXR support was in place.

BUG: 458054

Test Plan

Build Krita and run the new tests.
