[llvm] Handle Windows line endings in tag-html test (PR #113000)

[Daniel Paoliello via llvm-commits]

https://github.com/dpaoliello created https://github.com/llvm/llvm-project/pull/113000

The tag-html.test has been failing for me and [in CI](https://buildkite.com/llvm-project/github-pull-requests/builds/111277#0192a122-c5c9-4e4e-bc5b-7532fec99ae4) if Git happens to decide to check out the baseline file with Windows line endings.

This fix for this is to call `dos2unix` to strip Windows newlines from the baselines files in the test output directory before embedding them.
