fmt v11 support

[ArmstrongCN]

The problem

BMF currently depends on fmt v8, which causes dependency conflicts when downstream projects use newer versions of fmt (e.g., v9-v11). This forces downstream developers to resolve version mismatches manually, increasing integration costs.

Request

Update BMF to be compatible with fmt v8 through v11.

Thanks for your attention of this project.

In my opinion, it's a good point that enhance the compatibility of BMF.
However, I believe this issue shouldn't rely on ByteDance's internal team, as this is (maybe) not an internal usage scenario. This doesn't mean BMF is unwilling to support your environment, but rather that we hope community developers can help us improve the project and make it applicable to more use cases.

So, if you will submit patches for this, we'd be happy to assist you. Otherwise, resolving this compatibility issue might take some time - you know, work is always busy.

It's just my personal idea, wish to help you understand this project, I am one of Committers in this project but not work in ByteDance, so i really hope more developers join us to make this project be better.

Anyway, i'll tag this issue as enhancement.
