Stabilize `core::range::{legacy, RangeFull, RangeTo}`

Stabilize `core::range::legacy` and the re-exports of unchanged range types, so all range types can now be imported from within `core::range`. Newly stable API:

```rust
use core::range::RangeFull;
use core::range::RangeTo;
use core::range::legacy::{Range, RangeFrom, RangeInclusive, RangeToInclusive};
```

Compared to what is in the comment, I made a few exclusions:

1. At rust-lang#125687 (comment), @sendittothenewts suggested not to stabilize `core::range::RangeBounds` in case we want to reuse that name for a replacement based on `IntoBounds`. I have excluded it here so we can discuss further. `range_into_bounds` tracking issue: rust-lang#136903
2.   `one_sided_range` types should probably just move into this module rather than being exported, since they are unstable. Added an unresolved question at rust-lang#69780.
3. Similarly, `step_trait ` is unstable so we could just move `crate::iter::Step` if `core::range` is a better home. Added an unresolved question at rust-lang#42168.

Since this is the last thing in `new_range_api` that isn't tracked elsewhere:
