* build: move to the Rust 2021 edition

Since the MSRV of `naga` [is currently 1.56][msrv], I don't think there's a strong reason to stay
with the 2018 edition, and there _are_ a [few good reasons][edition-guide] to move to the 2021
edition.

I did this migration mostly automatically, per [official Rust guidelines]:

```sh
$ cargo fix --edition --all-targets
$ sed -i Cargo.toml 's/2018/2021'
$ cargo fix --edition-idioms --allow-dirty # doesn't change anything
```

The only manual edit needed to stymie a new warning introduced was the removal of the `TryFrom`
import in several modules, since it's now in the 2021 prelude.

* refactor(wgsl-in): use `pat` instead of `pat_param` again

How we were using `pat` in the Rust 2018 edition is actually the use case that
Rust 2021's `pat` fragment specifier is intended to satisfy. So, let's just use
that!
