Update Autotools to correctly configure oneAPI (#3751)

* Update Autotools to correctly configure oneAPI

Splits the Intel config files under the Autotools into 'classic'
Intel and oneAPI versions, fixing 'unsupported option' messages.

Also turns off `-check uninit` (new in 2023) in Fortran, which kills
the H5_buildiface program due to false positives.

* Enable Fortran in oneAPI CI workflow

* Turn on Fortran in CMake, update LD_LIBRARY_PATH

* Go back to disabling Fortran w/ Intel

For some reason there's a linking problem w/ Fortran
