…l-emscripten cmd
This moves the emsdk install from `{emsdk_cache}/{emscripten_version}` to
`{emsdk_cache}/{emscripten_version}/emsdk` so that we can put the prefix at
`emsdk_cache_dir/{emscripten_version}/prefix.
I moved the data about mpdec & libffi version, url, and shasum into config.toml along
with the emscripten version. Then as a cache key I write the library config section to
disk in the prefix dir like `{libname}.json`. I write it as a json file since tomllib
can't write toml. On subsequent builds, if prefix/{libname}.json contains the same data
then we can skip a rebuild.
I also added an install-emscripten command to make it easy to get this directory
structure correct.
