Function find_workspace_path

pub fn find_workspace_path(path: &str) -> PathBuf

Find the absolute path to a file or a directory in the workspace. The input path should be the relative path of the file or directory from workspace root.

For example, if the greptimedb project is placed under directory “/foo/bar/greptimedb/”, and this function is invoked with path = “/src/common/test-util/src/lib.rs”, you will get the absolute path to this file.

The return value is PathBuf. This is to adapt the Windows file system’s style. However, the input argument is Unix style, this is to give user the most convenience.
