This now includes support for the 'wasm-wasi-component' module.

This targets the upcoming 1.32.0 release which is required by
wasm-wasi-component. However of course the 1.32.0 tag doesn't exist yet,
so there will be a small window where this image won't build.

Thus

  $ make build-wasm

will build _both_ the 'wasm' & 'wasm-wasi-component' modules.

The minimum version required to build wasmtime 17 which is required by
wasm-wasi-component is 1.73.0

But no point not using the latest version.

This also now needs the libclang-dev package installed, we install this
via MODULE_PREBUILD_wasm.

- Go: Drop 1.20, Add 1.22
- Node: Drop 18, Add 21
- PHP: Add 8.3
- Ruby: Add 3.3

Perl and Python are still up-to-date with upstream releases

Regenerating the Dockerfiles also picks up the logging change from
183a1e9d634ae2fb129ce98f1ca8a16cbfdeac99

Saves on the order of 10 MBs of transfer for each build.

We call `rm -rf /usr/src/unit` later in this step, so the full repo has
never appeared in our published images anyway.

This allows to use /dev/stdout as application logs if users choose to do
so.
