WIP notes:
- `breakpoint()` - probably a test is possible but I haven't figured out how to do it yet.
- `is_debugger_present()` - has tests for `gdb` and `lldb`, which fail on some Windows configurations.
- debugger support: when the debugger breaks in `breakpoint()` it breaks inside the implementaiton, which isn't an optimal user experience. Perhaps LLDB (the debugger) can be thought to break on `breakpoint()` call site, similar to the `/JMC` option in MSVC but this is unrelated work to this patch.
