Build and test Windows aarch64 binaries natively (#18213)

Previously, aarch64 Windows binaries were cross-compiled on x86_64 hosts
in both build-release-binaries.yml and build-dev-binaries.yml, with the
wheel test steps explicitly skipped for aarch64 targets.

> [!NOTE]
> We need to ensure that the `github-windows-11-aarch64-8` runner exists
in the astral-sh org before this job can run.

Release binaries are now built on `github-windows-11-aarch64-8`, and
tests are enabled.

Dev binaries are now built on `windows-11-arm`, which is a standard
4-core ARM runner, with the timeout reduced from 25 to 10 minutes.
