[libc] Add memory fence utility to the GPU utilities (#91756)

Summary:
GPUs like to execute instructions in the background until something
excplitely consumes them. We are working on adding some
microbenchmarking code, which requires flushing the pending memory
operations beforehand. This patch simply adds these utility functions
that will be used in the near future.
