[libc-commits] [libc] [libc] Add GPU config file using the new format (PR #66635)

[Joseph Huber via libc-commits]

https://github.com/jhuber6 created https://github.com/llvm/llvm-project/pull/66635

Summary:
This patch copies a config file for the GPU similar to the
baremetal/embedded implementation. This will configure the
implementations of functions like `sprintf` and `snprintf` to be
compiled into more simple versions that can be run on the GPU. These
functions cannot be enabled yet as Vararg support hasn't landed, but it
will be used then.
