dev-libs/level-zero: new package

Header, loader and validation layer of oneAPI Level Zero. Used by recent
upstream versions of dev-libs/intel-neo.

Note that USE=test is a no-op for now because even though upstream
provides a CMake option to disable the building of tests, there aren't
actually any tests yet - at least in the release tarball.
