Update windows-sys version compatibility

[complexspaces]

This PR technically updates windows-sys, but more importantly it makes some changes to allow arboard to work with either 0.52 (more common) or 0.59 versions of the crate. This change's goal is to make it easier to balance the desires of parties who want the latest version in their tree (and to help the ecosystem move along) with those who are stuck with older versions and don't want their build times or lockfiles damaged.

It accomplishes this via three parts:

• Making changes to the windows.rs module to abstract over some function parameter and return value changes that have been made in the past.
• Using a range specifier in arboard's Cargo.toml
• Implementing CI testing to prevent accidentally using newer features that don't exist in 0.52 which would break downstream builds. This is the most important part as it helps verify our code is actually compatible with this version range.

The idea is based off many similar changes being made across crates.io, including winapi-util, errno, is-terminal, and many others to reduce version churn for users.

Looking at the CI run you can see that we download + check 0.59 of windows-sys in the new job, which succeeds, confirming there are no cargo version conflicts and that arboard's source is compatible with both library versions:

Locally running the same steps demonstrates the same.
