We add support for creating `VT_ERROR` variants via `__construct()`, and allow casting to int via `variant_cast()` and `variant_set_type()`. We do not, however, allow type conversion by other means, to avoid otherwise easily introduced type confusion. VB(A) also only allows explicit type conversion. We also introduce `DISP_E_PARAMNOTFOUND` which might be the most important `scode` for this purpose, since this allows to skip optional parameters in method calls. Closes GH-8886.
