Fix the arguments for std.windows.syserror.wenforce

This request contains the following changes:

- The argument types of `wenforce` in `StdDdoc` version are different from `Windows` version: `wenforce(T, string, size_t)(T, lazy string)` and `wenforce(T)(T, lazy string, string, size_t)`.
  They should have the same argument types.

- The second argument type should be `lazy const(char)[]` instead of `lazy string` to be consistent with the argument type of `std.exception.enforce`.
