execTEnumGetEnum now succeeds on Windows.

This was fixed by root-project/root#15408.
The failure on Windows was due to typeinfo(enum_type) returning a name
with the format enum enumname and until the addition (in that PR) of
the name normalization step, this was incorrectly handled by TEnum::GetEnum
