197de78f - [clang-doc] create a separate cmake file for clang-doc's lit tests (#165935)

[clang-doc] create a separate cmake file for clang-doc's lit tests (#165935) To avoid depending on all of the tools in clang-tools-extra, the `check-clang-extra-clang-doc` target is specialized in its own CMake file in clang-tools-extra/test/clang-doc. This eliminates around 800 files to be processed when building that target, plus linking every tool. Similar to [#155929](https://github.com/llvm/llvm-project/pull/155929).
