This attempts to reduce the total number of dependencies we're using to do i686 builds from the whole of `gcc-multilib` to just what's actually needed for rustc to work.

Our main use case for the `apt-install` action (#60) is installing the packages we need to make `i686-unknown-linux-gnu` Rust programs build and run on 64-bit runners. The main thing it was trying to do was avoid `apt-get update` via caching as updating the index was adding some 7s to each build, unfortunately that didn't work out (#65). Another thing we can do is avoid installing the whole of `gcc-multilib` and disable the `needsrestart` hooks since we don't care about those. Instead it installs `libc6-dev-i386` and `lib32gcc-13-dev` which seem to be sufficient: see RustCrypto/crypto-bigint#1331. This adds an action we can use everywhere we're doing setup for `i686-unknown-linux-gnu` builds which gives us one place to do these specific kinds of optimizations that don't need to apply to `apt-get` as a whole like `apt-install` was trying to do.

The whole goal of this action was to get rid of the packages parameter so we can have one place to configure a minified list. This uses the `libc6-dev-i386` and `lib32gcc-13-dev` packages which were tested in RustCrypto/crypto-bigint#1331
