This PR adds initial support for listing all attributes of an object. It is exposed through a new `all_members` routine in `ty_extensions`, which is in turn used to test the functionality. The purpose of listing all members is for code completion. That is, given a `object.<CURSOR>`, we would like to list all available attributes on `object`.

Static binary operations using in
Basic functionality
This demonstrates type inference support for <str-literal> in <tuple>:
from ty_extensions import static_assert
static_assert("foo" in ("quux", "foo", "baz"))
static_assert("foo" not in ("quux", "bar", "baz"))
With variables
from ty_extensions import static_assert
x = ("quux", "foo", "baz")
static_assert("foo" in x)
x = ("quux", "bar", "baz")
static_assert("foo" not in x)
Statically unknown results in a type error
from ty_extensions import static_assert
def _(a: str, b: str):
static_assert("foo" in (a, b)) # error: [static-assert-error]
Values being unknown doesn't mean the result is unknown
For example, when the types are completely disjoint:
from ty_extensions import static_assert
def _(a: int, b: int):
static_assert("foo" not in (a, b))
Failure cases
from ty_extensions import static_assert
# We don't support byte strings.
static_assert(b"foo" not in (b"quux", b"foo", b"baz")) # error: [static-assert-error]
