Initial FP SDK contribution, scoped to the fp64 emulation feature per CCCL
review request. Adds:
- <cuda/fpemu> header set under libcudacxx/include/cuda/__fp (packed and
unpacked fp64 emulation; accuracy levels low/mid/high)
- example (examples/fp) and header-only unit tests
(test/libcudacxx/cuda/fp/units), each with a local Makefile
- feature documentation (docs/libcudacxx/fp.rst)
Internal bit-casts route through cuda::std::bit_cast. fpmp, benchmarks and the
CUDA accuracy/perf test suites will follow in subsequent PRs.
