[libc] Export a pointer to the RPC client directly (#117913)
Summary:
We currently have an unnecessary level of indirection when initializing
the RPC client. This is a holdover from when the RPC client was not
trivially copyable and simply makes it more complicated. Here we use the
`asm` syntax to give the C++ variable a valid name so that we can just
copy to it directly.

Another advantage to this, is that if users want to piggy-back on the
same RPC interface they need only declare theirs as extern with the same
symbol name, or make it weak to optionally use it if LIBC isn't

[libc] Remove RPC server API and use the header directly (#117075)
Summary:
This patch removes much of the `llvmlibc_rpc_server` interface. This
pretty much deletes all of this code and just replaces it with including
`rpc.h` directly. We still maintain the file to let `libc` handle the
opcodes, since those depend on the `printf` impelmentation.

This will need to be cleaned up more, but I don't want to put too much
into a single patch.

[libc] Make a dedicated thread for the RPC server (#111210)
Summary:
Make a separate thread to run the server when we launch. This is
required by CUDA, which you can force with `export
CUDA_LAUNCH_BLOCKING=1`. I figured I might as well be consistent and do
it for the AMD implementation as well even though I believe it's not
necessary.

8c6a6f1a70 [libc] Make RPC malloc implementation return 'nullptr' on alloc failure
Summary:
`malloc` is supposed to return `nullptr` if it fails, not exit with an
error code.

[libc] Use LLVM CommandLine for loader tool (#101501)
Summary:
This patch removes the ad-hoc parsing that I used previously and
replaces it with the LLVM CommnadLine interface. This doesn't change any
functionality, but makes it easier to maintain.

[libc] Change the GPU loaders to LLVM executables (#101442)
Summary:
I am going to rework these tools to just me LLVM tools. This patch is
pretty much NFC to set up the CMake for that.
