[FEA]: Debugger pretty-printers: cuda::std::complex/cuda::complex #10090
Description
Create a lldb and gdb pretty printer for cuda::std::complex/cuda::complex.
The printer should live under libcudacxx/share/libcudacxx/<debugger>/complex.py for each debugger.
In addition, the pretty printers should be exhaustively tested, with tests living under libcudacxx/test/debugging/complex. See the existing tests in that directory for inspiration.

Hi! I'd like to work on this one. My plan is to follow the
cuda::std::arrayprinter pattern from #10528: addcomplex.pyunderlibcudacxx/share/libcudacxx/gdb/andlibcudacxx/share/libcudacxx/lldb/, covering bothcuda::std::complexandcuda::complex(both store__re_/__im_, so one matcher can handle the two class templates), plus exhaustive tests underlibcudacxx/test/debugging/complex/using the existing harness.Note: I'll validate the gdb printer locally but don't have lldb available in my environment, so the lldb printer will mirror the gdb logic structurally and rely on CI for verification — flagging that upfront in case it needs extra review attention.
