Introducing option NB_SUPPRESS_WARNINGS to nanobind_add_module

[mijoku]

With this change compile commands generated by cmake for targets consuming nanobind use -isystem instead of -I for defining nanobind's header locations, which makes modern analysis tools (e.g. clang-analyzer) ignore them.

Hello @mijoku, given that a number of people have been requesting this feature, I am willing to change my mind and consider it. But not as a default -- this is something that the user will need to request explicitly.

Thanks for the feedback. I introduced option NB_SUPPRESS_WARNINGS to nanobind_add_module to enable the intended behaviour. I hope, the option-naming is to your liking. Otherwise, I'm more than happy to incorporate suggestions.
I also tried to include some documentation, but please adapt the wording to something more of your liking.

Thanks!
