Build a data transform.

This command looks in the current working directory for a `transform.yaml` file. It installs the appropriate build plugin, then builds a `.wasm` file.

When invoked, it passes extra arguments directly to the underlying toolchain.

For example, to add debug symbols and use the `asyncify` scheduler for `tinygo`:

```bash
rpk transform build -- -scheduler=asyncify -no-debug=false
```

Language-specific details:

TinyGo - By default, TinyGo are release builds (-opt=2) and goroutines are disabled, for maximum performance.
