  -----------
  [llvm-readobj][AArch64][ELF][PAC] Support ELF AUTH constants (#74874)

Reapply llvm/llvm-project#72713 after fixing formatted printing of
`uint64_t` values as hex (see failing build here
https://lab.llvm.org/buildbot/#/builders/186/builds/13604).

This patch adds llvm-readobj support for:

- Dynamic `R_AARCH64_AUTH_*` relocations (including RELR compressed AUTH
relocations) as described here:
https://github.com/ARM-software/abi-aa/blob/main/pauthabielf64/pauthabielf64.rst#auth-variant-dynamic-relocations

- `.note.AARCH64-PAUTH-ABI-tag` section as defined here
