[clangd] Change diskbackedstorage to be atomic
Summary:
There was a chance that multiple clangd instances could try to write
same shard, in which case we would get a malformed file most likely. This patch
changes the writing mechanism to first write to a temporary file and then rename
it to fit real destination. Which is guaranteed to be atomic by POSIX.
