This commit pulls apart the inherent attribute dependence of classes like EnumAttrInfo and EnumAttrCase, factoring them out into simpler EnumCase and EnumInfo variants. This allows specifying the cases of an enum without needing to make the cases, or the EnumInfo itself, a subclass of SignlessIntegerAttrBase. The existing classes are retained as subclasses of the new ones, both for backwards compatibility and to allow attribute-specific information. In addition, the new BitEnum class changes its default printer/parser behavior: cases when multiple keywords appear, like having both nuw and nsw in overflow flags, will no longer be quoted by the operator<<, and the FieldParser instance will now expect multiple keywords. All instances of BitEnumAttr retain the old behavior.
