Adds a tool/yarn helper script that uses specific versions of yarn and
node, downloading them if necessary.
Modeled after tool/go (and the yarn and node Redo scripts from the
corp repo).
Also allows the path to yarn to be overidden (in case the user does not
want to use this script) and always pipes yarn output (to make debugging
and viewing of process easier).

When using tsconnect as a module in another repo, we cannot write to
the ./dist directory (modules directories are read-only by default -
there is a -modcacherw flag for `go get` but we can't count on it).
We add a -distdir flag that is honored by both the build and serve
commands for where to place output in.
Somewhat tedious because esbuild outputs paths relative to the working
directory, so we need to do some extra munging to make them relative
to the output directory.

Runs a Tailscale client in the browser (via a WebAssembly build of the
wasm package) and allows SSH access to machines. The wasm package exports
a newIPN function, which returns a simple JS object with methods like
start(), login(), logout() and ssh(). The golang.org/x/crypto/ssh
package is used for the SSH client.
Terminal emulation and QR code renedring is done via NPM packages (xterm
and qrcode respectively), thus we also need a JS toolchain that can
install and bundle them. Yarn is used for installation, and esbuild
handles loading them and bundling for production serving.
Updates #3157
