[Tizen] Revert "Pass zero length array as null" https://github.com/dotnet/coreclr...

Without this revert two coreclr tests fail if they are compiled with inputbubble and IL_STUB saving in ni:
- Interop/PInvoke/Array/MarshalArrayAsParam/AsDefault/AsDefaultTest/AsDefaultTest.sh
- Interop/PInvoke/Array/MarshalArrayAsParam/AsLPArray/AsLPArrayTest/AsLPArrayTest.sh

For both tests problem is exactly with array with 0 length, which is passed as NULL to native function.
But it should be a pointer to the non-existing element, and IL_STUB generated at runtime does exactly this.
