[LoongArch 2/n] Add ELF machine flag and relocs for upcoming LoongArch target

[SixWeining]

Summary

This patch adds necessary definitions for LoongArch ELF files, including
relocation types. Also adds initial support to ELFYaml, llvm-objdump,
and llvm-readobj in order to work with LoongArch ELFs.

Depends on D115772
