Remove windows i686 next-swc build target (#71041)

After #70995 investigated how much
our windows 32 bit build is actually leveraged and it seems it is not at
all. Also it seems Windows itself is [ending support for 32
bit](https://community.f-secure.com/total-en/kb/articles/29675-support-for-windows-10-32-bit-ending-on-september-30-2024#:~:text=Other%20Languages&text=F%2DSecure%20will%20stop%20supporting,a%20new%20version%20of%20Windows)
arch so no reason for us to continue supporting it.
