LOG: [libcxx] Passthrough the necessary CMake variables to benchmarks (#116644)

This addresses the issue uncovered by #115361. Previously, we weren't
building benchmarks in many cases due to the following block:

https://github.com/llvm/llvm-project/blob/e58949632e91477af58d983f3b66369e6a2c8233/libcxx/CMakeLists.txt#L162-L172

We need to passthrough the necessary variables into the benchmarks
subbuild and use correct syntax.
