This two libraries are failing to build with RISCV64. Fix it.
libjxl: Update to the last stable version and backport a patch fixing the build for RISCV64. Also stop using bundled libraries completely and instead build against system libcms2 instead of skcms. That matches how Debian builds this library.
highway: Update to last stable version, which builds fine on RISCV64
