JDK-8331414 - java.lang.classfile.Attributes class performs a lot of static initializations
Description
java.lang.classfile.Attributes has a static field for each predefined AttributeMapper and an extra field PREDEFINED_ATTRIBUTES initialized with a set of the mappers.

Exposing predefined mappers as static fields requires a lot of static initialization in one of the class involved in the JDK bootstrap.

In this enhancement I propose to expose all the mappers in a form of static methods to allow lazy initialization.
