Move windows-sys arm32 shim to c.rs

[ChrisDenton]

This moves the arm32 shim in to c.rs instead of appending to the generated file itself.

This makes it simpler to change these workarounds if/when needed. The downside is we need to exclude a couple of functions from being generated (see the comment). A metadata solution could help here but they'll be easy enough to add back if that happens.
