Deprecation warnings for old syntax: var x = _ (#18821)
6b12bf0 
First part #18861

* In `3.4` we emit the deprecation warning
* In `future` we emit we make this syntax an error
* Add patch. Not ideal because we need to use the full path of
`uninitialized`

```scala
//> using options -source future
var x: Int = _ // error
```
```diff
//> using options -rewrite -source 3.4-migration
- var x: Int = _
+ var x: Int = scala.compiletime.uninitialized
```
