  [Clang][AArch64] Add support for SHF_AARCH64_PURECODE ELF section flag (2/3) (#125688)

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.
Simlarly to ARM targets, generating object files with the
`SHF_AARCH64_PURECODE` flag set is enabled by the
`-mexecute-only`/`-mpure-code` driver flag.
