Update upp version, and add BUILD_TESTING option to prevent build of UPP testing (NOAA-EMC#1114)

Updated UPP version to develop as of 2026-05-15.

Also adds a `BUILD_TESTING=NO` flag to the UPP build to prevent build
of UPP unit tests. These assume the root CMAKE path is upp, which leads
to errors during build with unfound fix files.
