Package all tinygo commands

CS ran into some issue with the built version of tinygo that was used, so to aid debugging it's useful to package the full tinygo installation and all the commands.

This removes the custom main that we were providing and instead just adds some help text for rpk after build.

Additionally, always make sure to package binaryen on macos (this is needed for a hermetic toolchain)
