  [AArch64] Add support for SHF_AARCH64_PURECODE ELF section flag (1/3) (#125687)

Add support for the new SHF_AARCH64_PURECODE ELF section flag:
https://github.com/ARM-software/abi-aa/pull/304

The general implementation follows the existing one for ARM targets.
Generating object files with the `SHF_AARCH64_PURECODE` flag set is
enabled by the `+execute-only` target feature.
