[clang-tools-extra] [clang-doc] Fix benchmark not compiling (PR #185065)

[Erick Velez via cfe-commits]

https://github.com/evelez7 created https://github.com/llvm/llvm-project/pull/185065

CI didn't flag that the benchmark was using the outdated Ctx call after
when landing the Mustache MD patch since this benchmark isn't tested.
Also added missing libraries in CMake that prevented me from building
the benchmark locally.
