trigger range check with new type inference on nkIntLit [backport:1.6] (#23179)

fixes #23177

`changeType` doesn't perform range checks to see if the expression fits
the new type [if the old type is the same as the new
type](https://github.com/nim-lang/Nim/blob/62d8ca43063197272968b4acf8c7a1ef27874c54/compiler/semexprs.nim#L633).
For `nkIntLit`, we previously set the type to the concrete base of the
expected type first, then call `changeType`, which works for things like
range types but not bare types of smaller bit size like `int8`. Now we
don't set the type (so the type is nil), and `changeType` performs the
range check when the type is unset (nil).
