This is work towards unvendoring the Pyodide foreign function interface.
Prior to this point, we included a large amount of critical functionality with `--pre-js`.
So we could create an archive called `libpyodide.a` with the object files but to use it
you would have to pass `--pre-js _pyodide.out.js` at link time. This embeds all of this
stuff in an object file called `pyodide_pre.o` which goes in our archive so you get all
the needed js runtime by linking it.
Of course someone trying to use this still has to get the Python code onto the import
path, either using `--preload-file`, using Python to unpack it as a zip archive as we now
do, with zipimporter, or otherwise. They also will have to link `libpython.a` (is CPython
going to start distributing an Emscripten libpython?) and probably various other things.
We have to use a hack to inject the JavaScript code into the object files. The normal
`EM_JS` macro cannot handle arbitrary JavaScript code -- for example it fails with many
regex. Instead we manually generate write a C source file that does what we need using
`xxd`. The generated C code is similar to what `EM_JS` generates, but it uses an array
initializer rather than a string initializer for the characters avoiding the C preprocessor /
compiler's strange opinions about strings.
This adds rust toolchain into our docker image so we don't have to install it every time.
make rust command still exists, but I removed it from the docs. So now a user (who wants to build a package that requires rust) is responsible for installing rust toolchain in their build setup, which is reasonable I think.

Allows to execute `run_docker` in environments such as Github Actions.
Specifying the `--non-interactive` flag resolves the error "the input device
is not a TTY".

The installation is very fast, and this avoids having two copies of node
around. In particular, this avoids the need to monkey-patch uglify-js to
use the system node.
This can be further streamlined when #792 is merged
