Types of functions in hip_api.h not consistent with HIP runtime and GCC

1

For example, [in HIP-CPU `__ffsll`](https://github.com/ROCm-Developer-Tools/HIP-CPU/blob/1bf89aa04804fdb9ca6306a4d357cf4dfa5aa74d/include/hip/hip_api.h#L101) is defined with `std::uint64_t`: ```cpp std::uint32_t __ffsll(std::uint64_t x) noexcept { return hip::detail::bit_scan_forward(x); } ``` But in the [HIP runtime (CLR)](https://github.com/ROCm-Developer-Tools/clr/blob/5914ac3c6e9b3848023a7fa25e19e560b1c38541/hipamd/include/hip/amd_detail/amd_device_functions.h#L78) and [in GCC](https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html#index-_005f_005fbuiltin_005fffsll) it is...

missing hipLaunchKernel() - the version with void **args

It looks like HIP has provided since [2019](https://github.com/ROCm-Developer-Tools/HIP/pull/1353/files): ``` hipError_t hipLaunchKernel(const void* function_address, dim3 numBlocks, dim3 dimBlocks, void** args, size_t sharedMemBytes, hipStream_t stream); ``` HIP-CPU only provides hipLaunchKernelGGL with variadic...
