  -----------
  [JITLink] Support AArch64 big-endian (BE8) ELF objects (#225120)

The AArch64 ELF backend hard-coded ELF64LE, so aarch64_be 
objects failed to load. Follow the PPC64 multi-endian pattern: 
the graph builder, aarch64::applyFixup, ELFJITLinker_aarch64, 
and the link entry points (link_ELF_aarch64 / link_ELF_aarch64_be) 
are templated on llvm::endianness, with data fixups written in the 
compile-time target endianness and instructions always little-endian 
(the A64 ISA is word-invariant).
