When a class with a class variable is cloned we need to also copy the cvar cache table from the original table to the clone. I found this bug while working on fixing [Bug #19379]. While this does not fix that bug directly it is still a required change to fix another bug revealed by the fix in https://github.com/ruby/ruby/pull/7265

Copy cvar table on clone
When a class with a class variable is cloned we need to also copy the
cvar cache table from the original table to the clone. I found this bug
while working on fixing [Bug #19379]. While this does not fix that bug
directly it is still a required change to fix another bug revealed by
the fix in https://github.com/ruby/ruby/pull/7265
This needs to be backported to 3.2.x and 3.1.x.
