[red-knot] Infer subscript expression types for bytes literals (#13901)
## Summary
Infer subscript expression types for bytes literals:
```py
b = b"\x00abc\xff"
reveal_type(b[0]) # revealed: Literal[b"\x00"]
reveal_type(b[1]) # revealed: Literal[b"a"]
reveal_type(b[-1]) # revealed: Literal[b"\xff"]
reveal_type(b[-2]) # revealed: Literal[b"c"]
reveal_type(b[False]) # revealed: Literal[b"\x00"]
reveal_type(b[True]) # revealed: Literal[b"a"]
```
part of #13689
