psABI v2.20 added R_LARCH_CALL36 and removed R_LARCH_DELETE / R_LARCH_CFA.
R_LARCH_CALL36 was designed for function call on medium code model where
the 2 instructions (pcaddu18i + jirl) must be adjacent.
The LoongArch ELF psABI document has changed location and versioning
scheme; this revision is v2.10 in the old scheme. Notably this revision
brings initial capability of linker relaxation to LoongArch.

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.

Currently we don't support multiple SHT_SYMTAB_SHNDX sections
and the DT_SYMTAB_SHNDX tag currently.
This patch implements it and fixes the
https://bugs.llvm.org/show_bug.cgi?id=43991.
I had to introduce the `struct DataRegion` to ELF.h,
it is used to represent a region that might have no known size.
It is needed, because we don't know the size of the extended
section indices table when it is located via DT_SYMTAB_SHNDX.
In this case we still want to validate that we don't read
past the end of the file.

Summary:
Define ELF binary code for VE and modify code where should use this new code.
Depends on D79544.
