uninit_vec: fix false positive with set_len(0)

`set_len(0)` does not create uninitialized elements. Fixes a false positive with the following pattern:

```rust
fn copy_slice_into_vec(dst: &mut Vec<u8>, src: &[u8]) {
    dst.reserve(src.len().saturating_sub(dst.len()));
    unsafe {
        dst.set_len(0);
        std::ptr::copy_nonoverlapping(src.as_ptr(), dst.as_mut_ptr(), src.len());
        dst.set_len(src.len());
    }
}
```

Introduce mir::Unevaluated

Previously the distinction between unevaluated constants in the type-system and in mir was not explicit and a little confusing. Probably better to introduce its own type for that.

Fix ICE in `unnecessary_to_owned`

Compiler generated call `into_future` nodes return empty substs which we need when checking it's predicates. Handle this by simply exitting when we encounter one. This change introduces false negatives in place of the ICEs.

Clippy pre beta branch fix

Before beta is branched on Friday, I want to move the `unused_peekable` lint  that was added in this release cycle (1.65) to `nursery`. This lint was already reported twice (https://github.com/rust-lang/rust-clippy/issues/9456, https://github.com/rust-lang/rust-clippy/issues/9462) in a short time, so it is probably a good idea to fix it before it hits beta and then stable.

Update rust-analyzer documentation, mention linkedProjects

r-a uses the `rustc-dev` component from the rustup installed toolchain clippy specifies so it doesn't need to be manually installed. Also remove references to nightly r-a as the feature is long stable

I discovered `rust-analyzer.linkedProjects` recently and it has made working on the crates not referenced by the `clippy` crate so much nicer
