remove defaulting to unit
...
Types will no longer default to `()`, instead always defaulting to `!`.
This disables the associated warning and removes the flag from TyTuple

refactor ParamEnv::empty(Reveal) into two distinct methods
...
- `ParamEnv::empty()` -- does not reveal all, good for typeck
- `ParamEnv::reveal_all()` -- does, good for trans
- `param_env.with_reveal_all()` -- converts an existing parameter environment

Introduce UnpackedKind
This adds an `UnpackedKind` type as a typesafe counterpart to `Kind`. This should make future changes to kinds (such as const generics!) more resilient, as the type-checker will be able to catch more potential issues.

unused_unsafe: don't label irrelevant fns
Fixes #48131
Diagnostic bugfix to remove an errant note. Stops the search for an enclosing unsafe scope at the first safe fn encountered.
```rust
pub unsafe fn outer() {
fn inner() {
unsafe { /* unnecessary */ }
}
inner()
}
```
**Before:**
```
warning: unnecessary `unsafe` block
--> src/main.rs:3:9
|
1 | pub unsafe fn outer() {
| --------------------- because it's nested under this `unsafe` fn
2 | fn inner() {
3 | unsafe { /* unnecessary */ }
| ^^^^^^ unnecessary `unsafe` block
|
= note: #[warn(unused_unsafe)] on by default
```
**After:**
```
warning: unnecessary `unsafe` block
--> src/main.rs:3:9
|
3 | unsafe { /* unnecessary */ }
| ^^^^^^ unnecessary `unsafe` block
|
= note: #[warn(unused_unsafe)] on by default
