These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
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.
