`ELFDumper.cpp` implements the functionality that allows to get symbol versions.
It is used for dumping versioned symbols.

We have the https://bugs.llvm.org/show_bug.cgi?id=48670 bug which
suggests that `llvm-nm` also should print version names for symbols.

To achieve it, we can move out and reuse the code from `ELFDumper.cpp`.
This is what this patch do: it moves the related functionality to `ELFFile<ELFT>`.

I have a prototype of the patch for `llvm-nm` which uses this change and fixes PR48670.
I am planning to post it early on the next week, when it be ready for review.
