Rename class Attribute to PLAAttribute.

As PHP 8 introduces a built-in Attribute class, a name clash occurs
without this commit.

Class names are used by the Visitor class to dynamically build method
names. To avoid having to also rename the target methods, a class name
mapping is introduced for this purpose. This map may be augmented
whenever another similar case occurs.
