nodejs_packages: new package

This is a dummy package to specify and install required Node.js packages for the
target system.

The management of those packages and their dependencies is handled with
Yarn (run through host-nodejs) to maintain a reproducible offline cache that is
stored in local_src/nodejs_packages.

[uol: adjusted commit message and Kconfig menu file's help texts, integrated
Kconfig symbol NODEJS_PACKAGES_LICENSE, made NODEJS_PACKAGES_CACHE and YARN_LOCK
aware of PTXdist's concept of layers, made yarn, mkdir, install & cp more
verbose, suppressed echoing of diverse commands, removed one square bracket in a
shell test, let PTXdist bail out if yarn's frozen lock file does not exist at
all and wrapped install/cp into call of execute and world/execute]
