  [clang-repl] Implement IncrementalHIPDeviceParser for HIP device compilation (#218337)

This PR implements the IncrementalHIPDeviceParser. It takes each
incremental statement's device code and lowers it all the way to a
loadable HIP fat binary: linking the ROCm device libraries, running the
AMDGPU optimization/codegen pipeline, producing a .hsaco code object,
and embedding it as __hip_fatbin for the host runtime to register and
launch.

This PR only adds the parser class, wiring it into Interpreter.cpp and
the end-to-end tests will come in a follow-up.
