bitbake: lib/bb: Add bb.utils.rename() helper function and use for renaming

os.rename can fail for example an incremental build in Docker fails with:

OSError: [Errno 18] Invalid cross-device link

when source and destination are on different overlay filesystems.

Rather than trying to fix every call site, add a wrapper in bb.utils
for renames. We can then handle cross device failures and
fall back to shutil.move. The reason os.rename is still used is
because shutil.move is too slow for speed sensitive sections of code.

[YOCTO #14301]
