Append operator of
std::filesystem::path
will replace whole path when the param of "/" operation is an absolute path.In "All-in-one" mode, this shall cause ChunkCache removing the original vector data file when building chunk cache during/after load procedure.
This PR changes the ChunkCache path generation logic to a separate function in which will check whether the file path is absolute or not. If the file path is absolute, it removes the root path prefix and return concatenated file path.
