Oleaut: Support conversion of VT_SAFEARRAY into VT_ARRAY|type

[Robert Shearman]

ChangeLog:
Support conversion of VT_SAFEARRAY into VT_ARRAY|type.

Typelib variant types that cannot be converted should return
DISP_E_BADVARTYPE.

Don't call DispCallFunc if conversion of one of the arguments failed.
