RhpGetTickCount64: set the return type to match the definition in InternalCalls.cs

[yowl]

This PR fixes a mismatch in the return type for this function between the cpp implementation in MiscHelpers.cpp and the extern import in InternalCalls.cs where it is:

[DllImport(Redhawk.BaseName, CallingConvention = CallingConvention.Cdecl)]
internal static extern ulong RhpGetTickCount64();

The mismatch is a problem in the runtimelab NativeAOT-LLVM experiment where the linker, wasm-ld, complains and fails.

Return type changed from void to uint64_t.

Thanks,
