Rollup merge of #124019 - ChrisDenton:futex-raw-dylib, r=joboet

Use raw-dylib for Windows synchronization functions

Fixes #123999 by using the raw-dylib feature to specify the DLL to load the Windows futex functions from (e.g. [`WaitOnAddress`](https://learn.microsoft.com/en-us/windows/win32/api/synchapi/nf-synchapi-waitonaddress)). This avoids reliance on the import library causing that issue.

With apologies to ``@bjorn3,`` as it's currently necessary to revert this for cranelift.
