The GPU port of the LLVM C library needs to export a few extensions to the interface such that users can interface with it. This patch adds the necessary logic to define a GPU extension. Currently, this only exports a `rpc_reset_client` function. This allows us to use the server in D147054 to set up the RPC interface outside of `libc`.
