f79563a6 - Change IR graph print format to make it look more pythonic (#16986)

Change IR graph print format to make it look more pythonic (#16986) Summary: This removes curly braces from the outputs (we have indentation to indicate scopes), also adds ':' after graph and blocks declaration and removes ';' from the return line. ".expect" tests are updated to keep up with it.
