Failure compiling on windows with Intel OneAPI

[byrnHDF]

D:\a\hdf5\hdf5\build\ci-StdShar-Intel_deps\blosc2-src\blosc\directories.c(65,5): error: call to undeclared function 'rmdir'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
rmdir(dir_path);

Adding -Wno-implicit-function-declaration then causes a failure with linking because __cpu_mod is undefined in shuffle.c/blosc_get_cpu_features()

IntelOneAPI is available to use in github CI runners.

Hi @byrnHDF ! We would be happy to fix this. Would you mind to send a PR?

Not sure how to fix the failure - but Intel OneAPI is LLVM based and CMake identifies it as IntelLLVM.
HDF5 workflows use OneAPI for both CMake and autotools, see the intel-*.yml files for our steps.
The main step is:
- name: Install oneAPI (Linux) uses: fortran-lang/setup-fortran@v1 id: setup-fortran with: compiler: intel version: '2024.1'
