With this change rootcp will by default not print Info messages (same as rootcp.py), will print a `cp -v`-like output with -v and more detailed info with -vv.

This Pull request:
Depends on #20531.
Replaces
rootcp.pywith a native version in C++.Like for
rootlsandrootbrowse, this makesrootcpavailable even without python and, as a bonus, makes the tool significantly faster (the python version takes about 500ms just to start).The behaviour should be the same as the python version and it has the benefit of not crashing when trying to copy RNTuples (although RNTuple is not handled yet).
The new
rootcphas been currently mostly tested with our own roottest suite, but probably we want some more thorough testing before merging, especially if rootcp is used in experiments workflows.Other significant changes
rootlsandrootcp(will also be useful forrootmvand likelyrootmkdir): this is the code that basically converts a path like"file.root:a/b/*"to a tree of objects and directories.Checklist:
