Generate text file to save build path depth in coverage build (#3651)

Generate text file tools/test_driver/build_path_depth.txt to save build path depth.
gcov for cross build need directory strip to match build host directory and target directory.
Build path depth will be used to set GCOV_PREFIX_STRIP environment variable on target.
