Code model attribute

[asotona]

This is experimental serialization of code model into a custom method attribute.

I've performed brief comparison on BytecodeTest as a representant of class with majority of methods annotated with @CodeReflection.

Compiled size of the BytecodeTest class (with text-encoded code models) is 121288 bytes, CP contains 1612 entries.
Cleaned size of the class (removed text-encoded code models and their static initialization) is 32801 bytes, CP contains 1277 entries.
Size with models encoded in custom attributes is 74541 bytes, CP contains 1435 entries.

Proportional size of the custom attributes vs. text-encoded fields is 37% (47% of the CP entries).
