Add support for declared types to the semantic index. This involves a
lot of renaming to clarify the distinction between bindings and
declarations. The Definition (or more specifically, the DefinitionKind)
becomes responsible for determining which definitions are bindings,
which are declarations, and which are both, and the symbol table
building is refactored a bit so that the `IS_BOUND` (renamed from
`IS_DEFINED` for consistent terminology) flag is always set when a
binding is added, rather than being set separately (and requiring us to
ensure it is set properly).
The `SymbolState` is split into two parts, `SymbolBindings` and
`SymbolDeclarations`, because we need to store live bindings for every
declaration and live declarations for every binding; the split lets us
do this without storing more than we need.
The massive doc comment in `use_def.rs` is updated to reflect bindings
vs declarations.
The `UseDefMap` gains some new APIs which are allow-unused for now,
since this PR doesn't yet update type inference to take declarations
into account.
## Summary
Follow-up from #13268, this PR updates the test case to use
`assert_snapshot` now that the output is limited to only include the
rules with diagnostics.
## Test Plan
`cargo insta test`
Add `::is_empty` and `::union` methods to the `BitSet` implementation.
Allowing unused for now, until these methods become used later with the
declared-types implementation.

These are quite incomplete, but I needed to start stubbing them out in
order to build and test declared-types.
Allowing unused for now, until they are used later in the declared-types
PR.

## Summary
This PR adds a new `Type` variant called `TupleType` which is used for
heterogeneous elements.
### Display notes
* For an empty tuple, I'm using `tuple[()]` as described in the docs:
https://docs.python.org/3/library/typing.html#annotating-tuples
* For nested elements, it'll use the literal type instead of builtin
type unlike Pyright which does `tuple[Literal[1], tuple[int, int]]`
instead of `tuple[Literal[1], tuple[Literal[2], Literal[3]]]`. Also,
mypy would give `tuple[builtins.int, builtins.int]` instead of
`tuple[Literal[1], Literal[2]]`
## Test Plan
Update test case to account for the display change and add cases for
multiple elements and nested tuple elements.

## Summary
This PR adds support for control flow for match statement.
It also adds the necessary infrastructure required for narrowing
constraints in case blocks and implements the logic for
`PatternMatchSingleton` which is either `None` / `True` / `False`. Even
after this the inferred type doesn't get simplified completely, there's
a TODO for that in the test code.
## Test Plan
Add test cases for control flow for (a) when there's a wildcard pattern
and (b) when there isn't. There's also a test case to verify the
narrowing logic.

When a type of the form `Literal["..."]` would be constructed with too
large of a string, this PR converts it to `LiteralString` instead.
We also extend inference for binary operations to include the case where
one of the operands is `LiteralString`.
Closes#13224
Pull the tests from `types.rs` into `infer.rs`.
All of these are integration tests with the same basic form: create a
code sample, run type inference or check on it, and make some assertions
about types and/or diagnostics. These are the sort of tests we will want
to move into a test framework with a low-boilerplate custom textual
format. In the meantime, having them together (and more importantly,
their helper utilities together) means that it's easy to keep tests for
related language features together (iterable tests with other iterable
tests, callable tests with other callable tests), without an artificial
split based on tests which test diagnostics vs tests which test
inference. And it allows a single test to more easily test both
diagnostics and inference. (Ultimately in the test framework, they will
likely all test diagnostics, just in some cases the diagnostics will
come from `reveal_type()`.)
