Valgrind output when running JS-only test with `jsc`

* Copy `test.js` to `./WebKitBuild/WPE/Debug/`

* Enter WebKit WPE Flatpack:

  ./Tools/Scripts/webkit-flatpak --wpe --debug

* Run the test with Valgrind

  JSC_forceRAMSize=1G JSC_logGC=2 JSC_numberOfGCMarkers=2 \
  valgrind --read-var-info=yes --track-origins=yes \
    --log-file=./WebKitBuild/WPE/Debug/valgrind-jsc.log \
    ./WebKitBuild/WPE/Debug/bin/jsc ./WebKitBuild/WPE/Debug/test.js

`JSC_forceRAMSize=1G` is unlikely making any difference but I've been using it consistently initially hoping to make it a more representative env. of the platform where the crash was originally reproduced.
