[clang] [HLSL] standardize builtin unit tests (PR #83340)

[Farzon Lotfi via cfe-commits]

https://github.com/farzonl created https://github.com/llvm/llvm-project/pull/83340

This PR brings best practices mentioned to me on other prs and adds them to the existing builtin tests.

Note to reviewers: I put this up in two commits because the clang-format changes is making it hard to tell what actually changed.
use the first commit to check for correctness.
