Ben Sander 9c229f7530 Refactor hip_hcc.
Don't require setting __HIP_PLATFORM_HCC__ ; Instead check if compiler is HCC.
The functions here use HCC-specific functionality so only work with HCC.
ANd they work regardless of the __HIP_PLATFORM_HCC__ setting so don't
require that.

Also remove the "hcc_detail" extra hierarchy level for hip_hcc.h as
it is not necessary.  Remove hcc_detail/hip_hcc.h.

* @param [in] kernelParams
* @param [in] extra Pointer to kernel arguments. These are passed directly to the kernel and must be in the memory layout and alignment expected by the kernel.
* @param [in] startEvent If non-null, specified event will be updated to track the start time of the kernel launch. The event must be created before calling this API.
* @param [in] stopEvent If non-null, specified event will be updated to track the stop time of the kernel launch. The event must be created before calling this API.

* @warning kernellParams argument is not yet implemented in HIP. Please use extra instead. Please refer to hip_porting_driver_api.md for sample usage.
* HIP/ROCm actually updates the start event when the associated kernel completes.
