    devtool: add: fix node.js/npm handling with recipe specific sysroots
    
    The change over to recipe specific sysroots means that we can no longer
    get a known location simply from configuration for the npm binary - we
    need to get the recipe sysroot for nodejs-native, look there for npm if
    we need to check it's present, and add that to PATH when calling out to
    npm. Unfortunately this means anywhere we need to get that path we have
    to have parsed all recipes, otherwise we have no reliable way of
    resolving nodejs-native. Thus we have to change recipetool create to
    always parse all recipes (the structure of the code does not allow us to
    do this conditionally).
    
    In the worst case, if npm hasn't already been added to its own sysroot
    and we are fetching from a source repository rather than an npm
    registry, this gets a bit ugly because we end up parsing recipes three
    times:
    1) recipetool startup, which then fetches the code and determines it's
       a node.js module, finds that npm isn't available and then exits with
       a specific error to tell devtool it needs to build npm
    2) when we invoke bitbake -c addto_recipe_sysroot nodejs-native
    3) when we re-invoke recipetool
    
    This code is badly in need of refactoring, but now is unfortunately not
    the time to do that, so we're going to have to live with this ugliness
    for now.
    
    Fixes [YOCTO #10992].
