Updates uthash and makes some tweaks (#1928)
* Updates uthash from 2.1.0 to 2.3.0 * Moves uthash include and related to H5private.h * Defines HASH_NONFATAL_OOM so that out-of-memory doesn't abort() * Committing clang-format changes Co-authored-by: github-actions <41898282+github-actions[bot]@users.noreply.github.com>
