LOG: [libc] Remove old RPC host call extension for GPU (#120800)

Summary:
This was originally a hacked together function that served to just
implement some features for OpenMP. That has been moved into OpenMP
itself now that we have exported RPC properly. This can now be deleted.

Added: 
    

Modified: 
    libc/config/gpu/entrypoints.txt
    libc/config/gpu/headers.txt
    libc/include/CMakeLists.txt
    libc/src/__support/RPC/CMakeLists.txt

Removed: 
    libc/hdrgen/yaml/gpu/rpc.yaml
    libc/include/gpu/rpc.h.def
