[libc] Export GPU extensions to `libc` for external use 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`.

[libc] Move libc server handlers to a shared header (#117908) Summary: We can simply include this header from the shared directory now and do not need to have this level of indirection. Simply stash it with the other libc opcode handlers. If we were able to move the printf handlers to the shared directory then this could just be a header as well, which would HEAVILY simplify the mess associated with building the RPC server first in the projects build, then copying it to the runtimes build.

[libc] Increase RPC opcode to 32-bit and use a class byte (#116905) Summary: Currently, the RPC interface uses a basic opcode to communicate with the server. This currently is 16 bits. There's no reason for this to be 16 bits, because on the GPU a 32-bit write is the same as a 16-bit write performance wise. Additionally, I am now making all the `libc` based opcodes qualified with the 'c' type, mimiciing how Linux handles `ioctls` all coming from the same driver. This will make it easier to extend the interface when it's exported directly.

[libc] Change RPC opcode enum definition (#67439) Summary: This enum previously manually specified the value. This just made it unnecessarily difficult to add new ones without changing everything. This patch also makes it compatible with C by removing the `:` annotation and instead using the `LAST` method.
