RFR 8167636: jshell tool: Edit Pad should be in its own module

[Robert Field]

Note: jdk.internal.le and thus the jshell tool's ConsoleIOContext have a 
dependency on java.awt.event.ActionListener.
The former uses reflection to quietly ignore when it isn't present -- at 
a loss of functionality (functionality we use).
This code has a hack until I can discuss with Jan what the options are.
Ideally jdk.internal.le can lose it's dependency; Otherwise, I will 
change ConsoleIOContext to use reflection, which will mean a loss of 
shift-tab and shortcut+* functionality when java.desktop is not in the 
image.
