Differentiate files with the same name in bufferline

[norman784]

I think this will make a QoL improvement, now I updated and tried the bufferline and this is the first issue found. For example in a cargo workspace you have multiple lib.rs, main.rs or also a normal project mod.rs files. Maybe we can draw some inspiration from VScode in this regard, I'm not sure how the bufferline.nvim solves it.

I have a pull request that fixes this issue: #13344
It still needs review, but you can use it for yourself for now.
