Rename scripting libs and plugin - invert embeddable suffix

now regular, unshaded libs, are named with suffix `-unshaded`, while
former `-embeddable` ones named without any suffix. This will encoursge
use of the shaded libs by default, avoiding conflicts with 3-party
libs packed into the `kotlin-compiler`.
Note, that only the "frontline" libs are renamed to avoid switching
problems, the ones that not normally used directly are left as is,
including the `kotlin-compiler` itself.
