Version 0.51.0

[kennykerr]

As requested by #2603, this update includes the first published update to the windows crate in 5 months. As a reminder, updates are only published by request.

• This includes a semver-compatible update to the windows-targets crate.
• The windows crate now depends on the windows-core crate.
• The windows, windows-core, windows-implement, and windows-interface crates have been bumped to version 0.51.0 as there have been breaking changes.
• The windows-targets crate has been bumped to version 0.48.2 as it remains compatible with previous versions.
• Notably, an expanded set of WDK APIs are now available.
• Other crates will not be updated at this time.

Fixes: #2603

@kennykerr are you sure windows-bindgen/windows-metadata don't need an update? They generate calls to ::windows::imp::interface_hierarchy!(), but these have moved into the core.

::windows::core::imp::interface_hierarchy!() would also be inconvenient because the macro internally references ::windows_core and requires the windows-core crate to be in the dependencies list too.

I only publish crates upon request and only the windows crate was requested. I'm also actively working on the extensibility provided by those other crates so I'm eager to continue refining that before I publish another update.

And yes, it is an unfortunate side-effect of the windows-core crate that this additional dependency is necessary. I'm still mulling over how to address that most elegantly.

Opened an issue to request a release, but still surprised that this has te be requested explicitly.
