chore(ci): fix windows test

[lilnasy]

CI on main seems to be failing since snapshot based tests were introduced.

This PR includes two fixes:

• handling of backslashed paths when generating test code
• normalization of crlf which, were counted as two line breaks by snapshot comparison

Looks like windows test job doen't run on pull requests or feature branches, it only runs on main. You can review its status on my fork's main workflow run: https://github.com/lilnasy/oxc/actions/runs/18458898920.

Pull Request Overview

This PR fixes CI test failures on Windows by addressing path and line ending compatibility issues in the snapshot-based testing system. The changes ensure that tests run correctly on Windows by normalizing path separators and handling CRLF line endings.

• Normalizes CRLF line endings to LF for consistent snapshot comparison across platforms
• Converts Windows backslash path separators to forward slashes in generated test code
• Adds a utility function to handle newline normalization
