Add check to enforce literal syntax for Python builtin types
This check requires authors to initialize empty or zero builtin types
using the literal syntax (e.g., `{}` instead of `dict()`).
Authors may ignore this requirement for certain builtins using the
`--ignore` option.
Authors may also forbid calling `dict()` with keyword arguments
(`dict(a=1, b=2)`) using the `--no-allow-dict-kwargs` flag.
