Sync to upstream/release/676 (#1856)
We're back on track after the long weekend!

## General 
- `clang-format`ed new code. Keep your code tidy!
- Disable some Luau tests that are broken currently.
- Enable fragment autocomplete to do tagged union completion for modules
typechecked in the old solver.

## New Type Solver
- Fix false positives on generic type packs in non-strict mode.
- Update type signature of `setmetatable` to be `<T, MT>(T, MT) ->
setmetatable<T, MT>`.
- Make local type aliases available in type functions. For example:
```
type Foo = number
type Array<T> = {T}

type function Bar(t)
  return types.unionof(Foo, Array(t))
end
```

## VM/Runtime
- Make sure `lua_unref` doesn't accept refs which did not exist in the
table.
