Fix wxAffineMatrix2D::Translate() to multiply on the left.

Browse Source 
The affine transform was previously multiplied by the translation matrix on
the right but this was incompatible with both the MSW version of the same
method and all the other methods of the generic version.

So multiply the transform by the translation on the left, as everywhere else.

Closes #13875.
