rust_analyzer: make all paths in rust-project.json absolute
This is a step towards supporting automatic project discovery (bazelbuild#2755). Relative paths are resolved against the location of rust-project.json, but in auto-discovery this is the location of the BUILD file being discovered, not the workspace root. We already use absolute paths for generated files, so rust-project.json is not workspace-independent today. The alternatives seem more complex for little gain: - Only use absolute paths for auto-discovery mode, relative otherwise. - Use ../../ to express all workspace paths relative to the BUILD. See bazelbuild#2755 (comment)
