Fix 'Malformed class name' errors in typeName and related implementations

[jared-barocsi]

Replaces instances of getClass.getSimpleName in typeName, which is problematic in Java 8, with a common utility function (which just bundles the default Module.desiredName logic). Also disallows mixing HasAutoTypename into an anonymous Record, which is prone to generating Malformed class name errors.

Compiler plugin change was validated by attempting to compile anonymous Bundle with HasAutoTypename classes, with positive erroring.

Contributor Checklist

Type of Improvement

• Bugfix

Desired Merge Strategy

Squash

Release Notes

• Introduce a simpleClassName utility object that emulates a getClass.getSimpleName call without throwing Malformed class name exceptions when Java 8 is used. typeName and all related implementations use this function now instead of getClass.getSimpleName.
• HasAutoTypename can no longer be mixed into an anonymous Record; the compiler plugin now reports this as a compilation error.

are there any tests we should add? For inner class and or anonymous record?

I'm not able to add tests since it's a compiler step, the spec would fail compilation if I attempted to mix HasAutoTypename into an anonymous record.
