In D116750 <https://reviews.llvm.org/D116750>, the `clangFrontend` library was added as a dependency of `LexTests` in order to make `clang::ApplyHeaderSearchOptions()` available. This increased the number of TUs the test depends on.

This patch moves the function into `clangLex` and removes dependency of `LexTests` on `clangFrontend`.
