[flang-rt] Enable more runtime functions for the GPU target (#183649 )

Summary:
This enables primarily `stop.cpp` and `descriptor.cpp`. Requires a
little bit of wrangling to get it to compile. Unlike the CUDA build,
this build uses an in-tree libc++ configured for the GPU. This is
configured without thread support, environment, or filesystem, and it is
not POSIX at all. So, no mutexes, pthreads, or get/setenv.

I tested stop, but i don't know if it's actually legal to exit from
OpenMP offloading.

The LLVM/Offload Subproject

The Offload subproject aims at providing tooling, runtimes, and APIs that allow users to execute code on accelerators or other "co-processors" that may or may not match the architecture of their "host". In the long run, all kinds of targets are in scope of this effort, including but not limited to: CPUs, GPUs, FPGAs, AI/ML accelerators, distributed resources, etc.

For OpenMP offload users, the project is ready and fully usable. The final API design is still under development. More content will show up here and on our webpage soon. In the meantime, people are encouraged to participate in our meetings (see below) and check our development board as well as the discussions on Discourse.

Meetings

Every second Wednesday, 7:00 - 8:00am PT, starting Jan 24, 2024. Alternates with the OpenMP in LLVM meeting. invite.ics Meeting Minutes and Agenda
