Remove Boost.Bind usages.

[gogagum]

This PR replaces boost::bind usages with lambdas, so Boost.Bind can be removed from dependances.

I will make an attempt of doing some workaronds for Clang.

Thanks for your effort to improve Boost.Graph, it's really appreciated!
However, I strongly recommend you watch this video about bind and then consider what change you want to make: https://youtu.be/zt7ThwVfap0?si=47AbaJkWFh-VrnBc

Well, the speaker recommends to avoid std::bind. Do you mean this? I just tried to replace boost::bind with std::bind where possible to make minimal difference. It is not a problem to replace all std::bind usages with lambdas.

Yeah, I think replacing one bind with another is not really worth doing when it could be replaced with something even better.

I requested changes, but really they're just questions/suggestions. This code is good to go if there is a reason for everything.

Great, thanks for this improvement!
