Move context classpath utils from script-util to scripting-jvm

since it is the right place to have it in the new structure.
Solves the problem that script-util classes not found then script
definition with context classpath is loaded by the scripting compiler
plugin, since script-util is not packed into embeddable plugin.
The old context utils are deprecated and in fact wrap the new utils.
#KT-26828 fixed (in fact - partially, see another related commit)
