The newly released OIIO 2.5 (and changes in master) adjusts a few of its minimum dependencies (cmake, openexr, fmt) in ways that break some of our CI test cases for OSL 1.12, and also deprecated a helper method called ustringHash that OSL referenced in a few places.
These have already been addressed in the OSL main branch (what will soon be OSL 1.13), and in some cases OSL-next has also bumped some of the very same dependencies.
But this PR is dealing with the 1.12 branch, in which we cannot raise minimum dependencies that OSL requires. So here we are only adjusting which versions of those dependencies we are using or building for the specific tests in our CI matrix that use the sufficiently new OIIO that it needs the updated changes.
