[readobj][Arm][AArch64] Refactor Build Attributes parsing under ELFAtributeParser and add support for AArch64 Build Attributes (#128727)
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.
