Add windows_sys type definitions for ARM32 manually

[bdbai]

windows_sys bindings do not include platform-specific type definitions for ARM 32 architecture, so it breaks thumbv7a-pc-windows-msvc and thumbv7a-uwp-windows-msvc targets. This PR tries to add them back by manually inserting them together with the generated ones.

WSADATA is copied from the generated definition for x86. CONTEXT is copied from the definition before windows_sys is introduced (which is just an empty enum):

rust/library/std/src/sys/windows/c.rs

Line 802 in 4a18324

pub enum CONTEXT {}

.

Fixes #112265.

This looks good to me. I might want to think more about how to organise platform support but let's fix this issue first.

Could you add a short comment to arm_shim.rs explaining how it's included? Nothing long but it's not part of the normal module system so I'd like to make that clear for anyone reading.

@ChrisDenton I have added some comments in df08f56. Does it makes sense?

[ChrisDenton]

Yep makes sense to me, thanks!
