  [libc] Add Multithreaded GPU Benchmarks (#98964)

This PR runs benchmarks on a 32 threads (A single warp on NVPTX) by
default, adding the option for single threaded benchmarks. We can
specify that a benchmark should be run on a single thread using the
`SINGLE_THREADED_BENCHMARK()` macro.

I chose to use a flag here so that other options could be added in the
future.
