Summary:
The C function `eina_hash_del_by_data` requires the same value that was
passed to the `add` function. As C# hashes store stuff through pointers
due to marshalling, this makes it hard to pass the same pointer for it.
So this functionality is implemented at C# level instead of relying on
the native function directly.
Fixes T8198
Thanks to @brunobelo and @singh.amitesh for the test case.
