Location of half.hpp

[trixirt]

On the rocm-6.0.0 tag on Fedora Rawhide and gfx90a

There are many build errors similar to
MIOpen/test/serialize.hpp:33:10: fatal error: 'half/half.hpp' file not found
33 | #include <half/half.hpp>
| ^~~~~~~~~~~~~~~

On Fedora half.hpp is part of the system supplied headers and is installed to the system's /usr/include
Adding the half/ to the path makes it impossible to correct.
The location of half.hpp should be determined in the cmake infra and added as a -I
and just include <half.hpp>

@trixirt Have you successfully installed the dependencies as specified at https://github.com/ROCm/MIOpen#installing-the-dependencies?

Do you use CMAKE_PREFIX_PATH as shown at https://github.com/ROCm/MIOpen#for-the-hip-backend-rocm-35-and-later-run?

I am packaging MIOpen with the Fedora dependencies for Fedora.
The ROCm packages in Fedora are tracked here Fedora Heterogeneous Compute Sig

To be packaged in Fedora MIOpen must be packaged with the Fedora dependencies.
