[clang-tools-extra] [clang-doc] Cleanup CMake files and ensure benchmarks build (PR #185469)

[Paul Kirth via cfe-commits]

https://github.com/ilovepi created https://github.com/llvm/llvm-project/pull/185469

There's some poor formatting, and ClangDocBenchmark references several
targets that are required, but only because they're required for
clang-doc itself. We can just get those requirements from the clangDoc
target.

Additionally, we can make sure the benchmark builds as part of testing
when LLVM_INCLUDE_BENCHMARKS is set.
