Refactor readobj to integrate AArch64 Build Attributes under ELFAttributeParser. ELFAttributeParser now serves as a base class for: - ELFCompactAttrParser, handling Arm-style attributes with a single build attribute subsection. - ELFExtendedAttrParser, handling AArch64-style attributes with multiple build attribute subsections. This improves code organization and better aligns with the attribute parsing model. Add support for parsing AArch64 Build Attributes.
