[llvm] [Offload] Change HSA header search order (PR #95769)

[Joseph Huber via llvm-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/95769

Summary:
The HSA headers existed previously in `include/hsa.h` and were moved to
`include/hsa/hsa.h` in a later ROCm version. The include headers here
were originally designed to favor a newer one. However, this
unintentionally prevented the dyanmic HSA's `hsa.h` from being used if
both were present. This patch changes the order so it will be found
first.
