* Updated h5dump --xml
The location of the files HDF5-File.xsd and HDF5-File.dtd no longer exists, and
the files were added to the repo (PR #5490). Before the --xml is actually removed,
running the h5dump tests will fail. This PR updated h5dump and the expected output
to use the correct files' location and actually completed the ticket HELP-2668.
* Added missing expected files from the previous commit
* Fixed typo
* Made corrections per review feedbacks
* Committing clang-format changes
* Missing files from previous commit
