`statistics dump` command relies on `SymbolFile::GetDebugInfoSize()` to get total debug info size. The current implementation is missing debug info for split dwarf scenarios which requires getting debug info from separate dwo/dwp files. This patch fixes this issue for split dwarf by parsing debug info from dwp/dwo. New yaml tests are added. --------- Co-authored-by: jeffreytan81 <jeffreytan@fb.com>
