Reland [CGData] llvm-cgdata #89884 using `Opt` instead of `cl` - Action options are required, `--convert`, `--show`, `--merge`. This was similar to sub-commands previously implemented, but having a prefix `--`. - `--format` option is added, which specifies `text` or `binary`. --------- Co-authored-by: Kyungwoo Lee <kyulee@fb.com>
