update windows-sys dependency and adapt to breaking changes

[djdv]

I'm running the unstable version of everything, from the OS up to the Rust compiler.
In this environment I can no longer build/install sccache.
I haven't bisected when this stopped working but it seems to be tied to the windows-sys dependency

> cargo install --path=.

error: failed to compile `sccache v0.12.0 (C:\Users\Dominic Della Valle\Projects\3P\Rust\sccache)`, intermediate artifacts can be found at `C:\Users\Dominic Della Valle\Projects\3P\Rust\sccache\target`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

Updating it, and adapting the source code to match the API change seems to fix it.
The only change is related to using an explicitly typed null pointer versus an implicit pointer of integer 0.
Assuming this works fine on stable, but I'm sure the CI will let us know.

Specifically I did this:
cargo update --verbose --breaking -Z unstable-options -p windows-sys
And then edited src\commands.rs to conform to the breaking changes.

Oh boy....

I'll check the style rules. Assuming the toml must be single line like it was before.

Curious that the tests are failing with the same problem AFTER applying the patch.
I'll look at this later but not confident I'll be able to find the root of the problem.
