An ELF file's .note.gnu.property indicates arch features supported by the file. These features are extracted by arch_parse_elf_property() and stored in 'arch_elf_state'. Introduce x86 feature definitions and arch_setup_elf_property(), which enables such features. The first use-case of this function is Shadow Stack. ARM64 is the other arch that has ARCH_USE_GNU_PROPERTY and arch_parse_elf_ property(). Add arch_setup_elf_property() for it. Signed-off-by: Yu-cheng Yu <redacted>
