`Vec::push` in consts MVP
Example:
```rust
const X: &'static [u32] = {
let mut v = Vec::with_capacity(6);
let mut x = 1;
while x < 42 {
v.push(x);
x *= 2;
}
assert!(v.len() == 6);
v.const_make_global()
};
assert_eq!([1, 2, 4, 8, 16, 32], X);
```
Oh this is fun...
* We split out the implementation of `Global` such that it calls `intrinsics::const_allocate` and `intrinsics::const_deallocate` during compile time. This is achieved using `const_eval_select`
* This allows us to `impl const Allocator for Global`
* We then constify everything necessary for `Vec::with_capacity` and `Vec::push`.
* Added `Vec::const_make_global` to leak and intern the final value via `intrinsics::const_make_global`. If we see any pointer in the final value of a `const` that did not call `const_make_global`, we error as implemented in rust-lang/rust#143595 .
r? `@rust-lang/wg-const-eval`
To-do for me:
* [x] Assess the rustdoc impact of additional bounds in the method
* [x] ~~Increase test coverage~~ I think this is enough for an unstable feature.

`vec_recycle`: implementation
Tracking issue: rust-lang/rust#148227
Going with the `TransmuteFrom` approach suggested in https://github.com/rust-lang/libs-team/issues/674#issuecomment-3457795183 , but a bit simplified.
Currently does not work in some places where it should due to the limitations of the current implementation of the transmutability analysis: https://github.com/rust-lang/rust/issues/148227#issuecomment-3478099591

Closes rust-lang/rust#143813
I noticed that `from_parts_in` do the similar things like `from_raw_parts_in`, so I add the UB check in the last commit. If it is not appropriate, I will remove it.
And I fix a typo in the first commit.

Put the alloc unit tests in a separate alloctests package
Same rationale as https://github.com/rust-lang/rust/pull/135937 . This PR has some extra complexity though as a decent amount of tests are testing internal implementation details rather than the public api. As such I opted to include the modules containing the types under test using `#[path]` into the alloctests package. This means that those modules still need `#[cfg(test)]`, but the rest of liballoc no longer need it.
