Stop building 32-bit Windows wheels

Upstream `contourpy` has stopped building these wheels in their latest
1.1.0 release. Partially, this was because they thought we did, but also
because NumPy will for 2.0, and it's more difficult to do with Meson. As
we shall also be porting to Meson, we might as well turn this off too.
