This is mainly for publishing an update of the windows-bindgen crate but also fixes a few minor readme and version issues to avoid confusion.

• The windows and windows-core crates are updated to 0.51.1 to update the readme but are otherwise unchanged.
• The windows-targets crate and arch-specific crates are updated to 0.48.3 to update the readme and bring the lib file names in line with the crate version.

Those are all semver-compatible updates.

• The windows-bindgen crate is updated to 0.51.1 and includes the new riddle-based metadata processing capabilities and is compatible with the windows and windows-core crates.
• The windows-metadata crate is updated to 0.51.1 and includes many refinements but is largely for internal use.

Those are major breaking changes.

The windows-sys crate will not be updated at this time.
