1f46b6e46e1454b91ff7ceb31853bc440952f8eb util: Work around libstdc++ create_directories issue (laanwj)
Pull request description:
Work around libstdc++ issue [PR101510] with create_directories where the leaf already exists as a symlink. Fixes#24257, introduced by the switch to `std::filesystem`. It is meant to be more thorough than #24266, which worked around one instance of the problem.
The issue was [fixed upstream](https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=124eaa50e0a34f5f89572c1aa812c50979da58fc), but unfortunately we'll have to carry a fix for it for a while.
This introduces a function `fs::create_directories` which wraps
`std::filesystem::create_directories`. This allows easiliy reverting the
workaround when it is no longer necessary.
