[LoongArch] Updates for the LoongArch ELF psABI v2.01 revision
The e_flags of existing object files are all 0x3 which happens to be compatible. From this commit on, all LoongArch objects produced with upstream LLVM will be of object file ABI v1, which is already supported by binutils' master branch (to be released as 2.40), and is allowed by the same binutils version to interlink with v0 objects so the existing distributions have time to migrate.
