In ClassUtils.forName(), we originally delegated to
ClassLoader.loadClass(), which does not support loading classes from
binary names for arrays (such as "[[I" for "int[][]" or
"[Ljava.lang.String;" for "String[]"); whereas, Class.forName() does
support binary names for arrays.
However, in Spring Framework 5.1.1 we switched from using
ClassLoader.loadClass() to Class.forName() in ClassUtils.forName() (see
gh-21867), which makes our custom handling of binary names for arrays
in ClassUtils.forName() obsolete.
In light of that, this commit removes our custom binary array name
handling support from ClassUtils.forName().
Closes gh-34291
