Add const generics test for all range types.

In addition to the regression test of `RangeInclusive` for rust-lang#70155, now all range types are checked for usability within const generics:

- `RangeFrom`
- `RangeFull`
- `RangeToInclusive`
- `RangeTo`
- `Range`

The test are moved from `test\ui\const-generics\issues\issue-70155` to `test\ui\const-generics\std\range` in anticipation of future similar tests for std types.
