Fixes for building SYCL backend for AMD GPUs

Browse Source 
- cmake has a hardcoded `onemkl` that will cause linker failure for AMD
  path and needs to be changed
- docfix: oneMKL compile needs `-DHIP_TARGETS` not `-DHIPTARGETS`
- docfix: modified cmake build parameters to pass in more linker flags,
  otherwise linking will fail (might be slight overkill, but without
  adding `-DCMAKE_SHARED_LINKER_FLAGS` it fails
