Add a J2CL compiler script (#7052)
J2CL runs a long pipeline of binaryen opts, including multiple invocations. This adds a
tool that simulates the same process manually, which can be easier to debug with
than running a full J2CL toolchain, which requires Bazel, etc. - this is just a few lines of
bash that does the same thing (at least in simple cases).
