RFR: 8295029: runtime/cds/appcds/LotsOfClasses.java fail with jfx

[Coleen Phillimore]

This removes the can-resize parameter for ClassLoaderData dictionaries. They can all resize now that the shared dictionaries are moved to the CompactHashtable. This also removes an unused/untested development option to disallow resizing.
Tested with tiers1-4 and tested with the failing test case. It can't be added because it requires outside code or simulated because it would be an expensive test to generate all those class files.  There's an existing test for resizing.
