  [LLD][ELF][AArch64] Add support for SHF_AARCH64_PURECODE ELF section flag (3/3) (#125689)

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. The
output section only has the `SHF_AARCH64_PURECODE` flag set if all input
sections have it set.
