The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.

update: actions/checkout@v2 to actions/checkout@v3 for all yaml files

Revert "update: actions/checkout@v2 to actions/checkout@v3 for all yaml files"

This reverts commit 7445e582b900f0f56f5f2bd9036aacab97ef28e9.

change GitHub Actions version v2 to v3

The current "This is supported" wording implies that it's possible to
still use the item on other configurations, but in an unsupported way.
Changing this to "Available" removes this ambiguity.
Some masks where defined as
```rust
const NONASCII_MASK: usize = 0x80808080_80808080u64 as usize;
```
where it was assumed that `usize` is never wider than 64, which is currently true.

To make those constants valid in a hypothetical 128-bit target, these constants have been redefined in an `usize`-width-agnostic way
```rust
const NONASCII_MASK: usize = usize::from_ne_bytes([0x80; size_of::<usize>()]);
```

There are already some cases where Rust anticipates the possibility of supporting 128-bit targets, such as not implementing `From<usize>` for `u64`.
resolve: Create dummy bindings for all unresolved imports

Apparently such bindings weren't previously created for all unresolved imports, causing issues like rust-lang#95879.
In this PR I'm trying to create such dummy bindings in a more centralized way by calling `import_dummy_binding` once for all imports in `finalize_imports`.

Fixes rust-lang#95879.

Update GitHub Actions actions/checkout Version v2 -> v3

Update `actions/checkout@v2` to `actions/checkout@v3` because of Node12 will be out of life after Aril 30, 2022 [[Reference](https://nodejs.org/en/about/releases/)].
`actions/xxxx@v3` use Node16 whose support lasts until April 30, 2024.
docs: add link from zip to unzip

The docs for `Iterator::unzip` explain that it is kind of an inverse operation to `Iterator::zip` and guide the reader to the `zip` docs, but the `zip` docs don't let the user know that they can undo the `zip` operation with `unzip`. This change modifies the docs to help the user find `unzip`.

Make some `usize`-typed masks definitions agnostic to the size of `usize`
