This represents the context for a proxy class. It seems `ProxyClassContext`
would be clearer. I suggest the context to have the accessFlags for a proxy
class rather than the boolean whether it's package private. The constructor
should check that it must be 0 or `Modifier.PUBLIC`. `FINAL` will be added to
the access flags when it generates the proxy class.

Perhaps name this method `proxyClassContext` that returns `ProxyClassContext`.

I suggest to keep the `getDynamicModule` method as creating a dynamic module of
a given class loader is a clear function. The context can be created in this
method body.
var targetModule = getDynamicModule(loader);
var pkgName = nonExported ? PROXY_PACKAGE_PREFIX + '.' +
targetModule.getName()
: targetModule.getName();
var context = new ProxyClassContext(targetModule, pkgName,
Modifier.PUBLIC);
