ui: Update NodeJS and Wasm toolchain

Uprev to Node 14.15.4 and Emscripten 2.0.12.
Also:
- Update the path in buildtools where both are
  checked out, moving them in the os-specific folder.
  This is to match what we do with other binaries and
  to allow using both OSes via docker or other VMs.
- Fix trace_converter.ts to deal with a subtle change
  in the ordering of javascript JS library:
  onRuntimeInitialized is now called *before* the init
  function returns (previously was posted on another
  task). This makes referring to the module object
  by capture an 'undefined mod' exception.
- Inline --em-config has been deprecated, move it to
  a file.
- Move node/npm wrapper scripts to /tools, so in the
  long run we can just tell to PATH=$(pwd)/tools in the
  instructions.
- Make everything consistently use //tools/node.
- Fix a bunch of places that were accidentally using
  the system npm rather than the hermetic one.

Test: manually tested (i) opening trace; (ii) open with
      legacy; (iii) converting and downloading a heapdump
      from the flamegraph.
